Abstract

This paper studies the trajectory planning for autonomous rendezvous and proximity maneuvering of a spacecraft near a non-cooperative spacecraft in an elliptical orbit using pulse-width pulse-frequency thrust. The problem is formulated by converting the continuous control input, output from the state dependent model predictive control, into a sequence of pulses of constant magnitude by controlling the thruster firing frequency and duration. The state dependent model predictive control is derived by minimizing the control error and control roughness of the modulated control input for a safe, smooth and fuel efficient approaching trajectory. The numerical results show that the proposed state dependent model predictive control with the pulse-width pulse-frequency modulation is able to effectively generate optimized trajectories using equivalent control pulses for the proximity maneuvering with less energy consumption.

Abstract

Professional Science Master’s (PSM) degree programs were established to educate students in both advanced STEM knowledge and business skills. The Master of Science in Professional Science (MSPS) program at Middle Tennessee State University (MTSU) was established in a partnership between science and business faculty to provide middle Tennessee with a highly trained, business-savvy workforce in three concentrations: Biostatistics, Biotechnology, and Health Care Informatics. Since then, it has added Actuarial Sciences, Geosciences, and Engineering Management. The Engineering Management MSPS concentration is a highly attractive career opportunity for students from a mechanical and mechatronics engineering background. The leading-edge engineering courses provide students with certifications in PMI Project Management, Six Sigma, and lean manufacturing, as well as providing additional education in safety processes and engineering management. The business courses–which are required of all MSPS students–prepare students for leadership and management roles, so that engineering management students graduate ready to both design the solutions and lead the their implementation. Students put all of their skills to practice in their capstone internship in industry, where more than 70% are eventually offered jobs. These graduates are then on a fast-track for the kinds of high-paying, in-demand manufacturing management jobs.

Abstract

Automotive weight reduction or lightweighting has been an important factor for every automaker in order to meet the CAFE (Corporate Average Fuel Economy) regulations of the particular country. Mass reduction versus increased strength and stiffness have been challenging to balance in real life due to other competing functional performance of a vehicle such as crash performance, aesthetics, corrosion resistance, cost, reliability and joining methodologies to mention a few. Steel and its alloys has been and still will be the dominant material used in an automobile. However, use of multi-material technologies with aluminum, magnesium, plastics and composites, together with steel is drawing the attention of many automakers. In this proposed keynote talk some of the above mentioned issues and CAFE regulations and how they can be addressed using lightweighting technologies will be broadly covered. Some details about using different grades and forms of steel and aluminum alloys for the body in white (BIW) components and the role of composite materials will be discussed. Some case studies developed by SAGA, CAR, and other industry experts will be discussed. Joining methodologies of multi-materials will also be discussed in this lecture. This proposed talk has been developed for engineering professors, students, engineers and technical personnel involved in all fields related to the automotive vehicle design or development. Additionally, this talk can be valuable to those with component design responsibilities in the above areas. Many of the concepts covered in the lectures are planned to be complimented by Q&A, which further enhances learner interactivity.

Abstract

VÚTS, a.s.,is engaged in the design and manufacture of special single-purpose machines. It equips them with its developed control systems that enable the implementation of the relevant technology. The Department for Mechatronics has been conducting application research of electronic cams based on HW and SW components of Yaskawa (Japan) for more than 10 years. Because electronic cam applications are related to proper control systems, a general control system was developed based on a state machine concept with manual and automatic modes. This concept is common in machine tool control systems. However, there is a fundamental difference in the automatic mode where the program logic of electronic cams is used to control the individual NC axes. The movement of working links or individual axes is derived from displacement laws, including the 1st and 2nd derivatives, which are utilized in feedforwards of speed and torque of the cascade control structure in the servo converter. The concept of the control system with electronic cams was used for a number of single-purpose machines, two of them will be mentioned. The first is a single-purpose machine for machining wooden slats of folding rulers. On this machine, there will be demonstrated the main features of electronic cams with the control system and their application issues, which is primarily to achieve the required positional accuracy,dependent on the dynamics of working movements. The second application is then a single-purpose experimental machine tool for milling and grinding technologies of conventional radial cams. Attention will also be paid to the issues of the input source data of motion functions of electronic cams and NC axes.

Abstract

Liquid fuels produced from various waste resources could replace fossil diesel use in stationary and mobile engines. These fuels could play a very important role in meeting the greenhouse gas (GHG) reduction targets. Waste resources such as waste cooking oil, paper industry sludge, anaerobic digested sludge, sewage sludge, chicken skin, lamb fats and nonedible oils were converted to biodiesels and liquid oils through thermochemical processes. The physical and chemical properties of these fuels were measured and the results were compared with the fossil diesel and biodiesel standard. These fuels were used in the compression ignition engines as neat (100%) or as blended with fossil diesel or biodiesel in various proportions. In this talk, an overview of the engine combustion and performance characteristics will be presented when these alternative fuels were used in the diesel engine. The advantages and limitations of using these fuels in diesel engines will also be discussed.

Abstract

Over the past thirty or so years, academics have been investigating the use of a range of machine learning algorithms for computational engineering. An example is using the finite element method to train a neural network to estimate the deflection of a loaded structure. The trained neural network is then used to perform stress analysis, for a structure it has not been shown before, without needing to use finite elements. Generally speaking, this type of work has not been particularly high profile and has not been adopted in commercial software packages. Many of the research outputs sound like parlour tricks and exist as curiosities in the back catalogue of scientific journals, far from practical application due to the limited computing capabilities, processing power and storage, available at the time the research was carried out. Nowadays, it is difficult to avoid the buzz phrases of artificial intelligence, data driven computing and cloud services. Suddenly, computers have sufficient power to reawaken these ideas and transform them into a new generation of simulation tools. If the predicted disruption to computational engineering was not already profound, consider the increasing maturity in natural language processing; the use of digital assistants is commonplace for making calls, playing music and shopping. In this paper, I will describe how the convergence of these technological advances will soon lead to the first generation of engineers who will discard their mouse, keyboards and touch screens and instead converse with their intelligent digital assistant: Alexa, the stress analysis engineer.

Abstract

Contemporary robot control methodologies have their origin in the classical control systems theory and practice. Except for the increased adoption of modern computers in the hardware implementation and adaptations of software, the design and analysis has been limited to the original knowhow. When the robotics field covered operations in mostly structured environments there was limited need to explorebeyond standard requirements of high speed and high repeatability. These along with the payload capacity, robot weight and power requirements provided the necessary specifications that could be met in most applications. The situation started to change when the environments became unstructured and not fully known. This was brought up by the emergence of mobile robot applications and interactions of human-robot in many applications. It gave rise to requirements that could not be satisfied with contemporary control systems methodologies. As a result, a new trust emerged, that of Artificial Intelligence. It provides tools to deal with situations that are basically complex, such as robots operating in unknown and continuously changing environments. It has provided an opportunity to use fundamental AI techniques to control thee systems operating in only partially known situations. There is a need to look at this quest from the critical point of view that AI serves well when the systems can be a priori properly trained or used in non-real time applications, ex. e-commerce, as opposed to robotics that requires real-time operation and adequate training thus posing limitations in the current use of AI.

Abstract

At the department of Mechanical and Materials Engineering (MME), students in the engineering technology program, must complete a capstone senior design (SD) project. Prior to fall semester, students are required to submit their SD idea to the faculty for input and approval. Some of the projects are company sponsored. Based on their problem statement and a detail background on their intended design ideas, the faculty will vote. Once the SD ideas are approved, the SD process starts with a written proposal. The next step is the design and analysis phase where students begin analyzing the components for material selection and size. Finally, a complete 3D assembly model is created with a set of fabrication drawings. The final step is the manufacturing/fabrication phase. Once the materials are gathered then the fabrication process to produce a functional prototype starts. The prototype will be tested to meet the objectives.

System paramenter identification is an important part of the modeling and control of systems. In many undergraduate courses, various first order system and second order system theories are taught as individual modules and assessed in a similar fashion. While students may be able to understand these concepts individually, they may struggle to determine which estimation method is needed when faced with an unknown system. To address this issue, students are given several boxes that contain unknown electrical circuits. Using step response data and frequency response data, students must determine the correct methods to estimate the appropriate system parameters necessary to model the system in each box. During this laboratory experiment, it is common to observe student groups trying to identify first order systems using second order techniques or using time domain techniques on frequency domain data. Through these mistakes and subsequent discussions with the groups, students gain a better understanding of the various techniques and the connections between previous theoretical coursework and upper-level design courses.

Abstract

Hybrid press mechanism is described as a 7 link mechanism driven by a servo motor and a condtant speed motor representing 2 DOF system.The mechanism includes seven links wth seven revolute joints and one prismatic joint. This confoguration is previously suggested as an alternative for servo presses indeed. Motion characteristics are specially chosen for metal shaping operations as case study. Ram output characteristics are studied for industral stamping operations first. Hybrid drive has offered programmability thus providing flexibility at the output. Mathematical model of the system is used while implementing PID control issues with Fuzzy. PID. Inverse kinetics issues are considered. Different Fuzzy structure designs are available; direct action type, fuzzy gain scheduling type, and hybrid fuzzy type. These designs are then studied, and implemented to hybrid compared with simulations on the base of performance indexes. Their performances are seen in Matlab® environment by using hybrid press mechanism described herein.

Abstract

Thin-film stretchable sensors are believed to have great applications on devices with curved surfaces. As one type of these sensors, electronic skins (e-skins) for pressure measurement have the potential to provide protection to the human body by feeding back the contact pressure. One of the applications is to monitor the contact pressure from a colonoscope to the colonic wall during a colonoscopy to prevent perforation and hemorrhaging. In this work, a new technique to make ultra-thin, highly stretchable electrodes on thin films has been developed. Then a three-layer tube-shaped tactile sensor with high conformability and stretchability has been successfully built. The pressure generated by various bending curvatures on a colonoscope was then investigated. Finally, a real-time pressure measurement with the whole sensing system on a fake colonoscope in a colon-simulator has been performed. The measured pressure was obtained and visualized on a computer screen. These experiments validated the applicability of the designed sensor and revealed the actual stress distribution on a tube-shaped e-skin sensor array in a colon-simulator. This research could be the starting point of the effort to upgrade the strategies of colonoscopy for safer operations and could provide new routines to optimize tactile sensor design for other medical applications.

Abstract

Earthquakes can generate large amounts of solid and liquid waste that threaten public health, make reconstruction difficult and affect the environment. Disaster waste can be generated by the actual disaster and later during the response and recovery phases. It is for this reason that waste management becomes a crucial issue for post-disaster recovery. This work develops the analysis and evaluation of different mechanisms by three performance indices: mechanical advantage, stiffness and manipulability, with the purpose of discriminate these configurations and select the optimal solution to provide the required movement and force by the reinforced concrete crusher machine. The initial configurations where selected based on common characteristics; they all are one degree of freedom mechanisms (DoF=1), and their input link represents the movement of a crank. From the analysis, it is concluded that the six bar mechanism in which output link performs as an oscillator presents the best characteristics for the desired implementation; with the length of each link and the position of the ground stablished, the needed input torque behavior was determined in order to keep the required output force along the compression movement able to crush the reinforced concrete. In this context, in the past, has been investigated the feasibility of using recycled materials in concrete by focusing on the fracture mechanism of the specimens and was observed that replacing natural stone aggregate with up to 30% of RSA can be effectively used. Despite all of this, rather than concern of send rubble to recycling process, a big problem in Mexico is to motivate construction companies to use this material in new buildings.
