This course is intended to teach modern systematic design techniques used in the practice of mechanical engineering. Methodology for the development of design objective(s), literature surveys, base case designs, and design alternatives are given. Economic analyses with an emphasis on capital investment and operating costs are introduced. Integrated product and process design concepts are emphasized with case studies. Students are encouraged to select their senior capstone design project near the end of the course, form teams, and commence preliminary work. A number of design projects are required of all students.
The principles of dynamics as applied to the analysis of the accelerations and dynamic forces in machines such as linkages, cam systems, gears trains, belts, chains and couplings. The effect these dynamic forces have on the dynamic balance and operation of the machines and the attending stresses in the individual components of the machines. Some synthesis techniques. Students also work in teams on a semester long project associated with the design of a mechanical system from recognizing the need through a detailed conceptual design.
Static and dynamic force analysis of mechanisms, dynamics of reciprocating and rotating machinery, balancing of machinery, friction and wear, vibration and noise control in machines, manipulators and robots, computer-aided design.
Introduction to the application of engineering analysis techniques and mathematical principles of mechanical engineering. In addition to analytical and computational techniques, case studies and project-based examples will be given.
This course addresses methodologies and tools to define product development phases and also provides experience working in teams to design high-quality competitive products. Primary goals are to improve ability to reason about design, material and process alternatives and apply modeling techniques appropriate for different development phases, as well as development of competitive product design and plans for its manufacture along with facilities layout simulation, testing and service. Topics covered are: user requirements gathering, quality function deployment (QFD), design for assembly, design for materials and manufacturing processes, optimizing the design for cost and producibility, manufacturing process specifications and planning, process control and optimization, SPC and six sigma process, tolerance analysis, flexible manufacturing, product testing and rapid prototyping.
Courses on advanced topics of current interest in Mechanical Engineering, including but not limited to any of the following: steam turbines, random vibrations, stability of nonlinear mechanical systems, stress waves in solids, lubrication theory, radiative heat transfer, mechanism design, buckling of metal structures.
