Mechanical engineering includes all aspects of design, development, control, and manufacture of mechanical systems and energy conversion systems. Mechanical engineering is essential to the proper design and manufacture of nearly every physical product in our modern world. As such, mechanical engineers are a fundamental resource for most industries, and they work in interdisciplinary environments. Mechanical engineers must have the ability to see broad perspectives across disciplines and industries and yet solve very local and specialized problems. The undergraduate curriculum addresses the education and training of mechanical engineering students and concentrates on two technical areas: (1) design and analysis of thermofluid systems for effective use of energy; and (2) design, analysis, and control of mechanical systems including the study of materials used in engineering. Educational efforts are channeled to expand the skills of prospective engineers not only in understanding fundamentals but also in developing competence in analyzing engineering systems.

COMBINED BACHELOR OF SCIENCE AND MASTER OF SCIENCE PROGRAM

The Department of Mechanical Engineering offers a combined degree program leading to the Bachelor of Science and a Master of Science open to mechanical engineering majors. Under the combined degree program, an undergraduate student begins taking courses required for a master’s degree before completing the requirements for the bachelor’s degree and typically completes the requirements for a Master of Science in Mechanical Engineering at the end of the fifth year.

Undergraduate students admitted to the combined degree program begin taking graduate classes during their senior year. They are required to enroll in the program between February of their junior year and December of their senior year. Students in this program will receive their bachelor’s degree after satisfying the standard undergraduate degree requirements. To earn the master’s degree, students must fulfill all the requirements for the degree, including the completion of 45 units of coursework beyond that applied to their bachelor’s degree and completion of the master’s thesis. No course can be used to satisfy requirements for both the bachelor’s degree and the master’s degree.

MECHANICAL ENGINEERING LABORATORIES

The Nanomechanics Lab houses a nanoindenter, a mechanical test instrument with nanometer displacement resolution and micro-Newton load resolution. In addition to measuring mechanical properties such as hardness and elastic modulus with high spatial resolution, the tip of the nanoindenter may be used to perform mechanical testing on MEMS devices.

The CAM and Prototyping Lab consists of two machine shops and a prototyping area. One machine shop is dedicated to student use for design and research projects. The second is a teaching lab used for undergraduate and graduate instruction. Both are equipped with modern machine tools, such as lathes and milling machines. The teaching lab also houses both 2-axis and 3-axis Computer Numerically Controlled vertical milling machines and a CNC lathe. Commercial CAM software is available for ease of programming. The prototyping area is equipped with a Stratasys FDM 3000 rapid prototyping system that utilizes fused deposition modeling to create plastic prototypes from CAD generated models. Also available are a Cyberware laser scanner and a Microscribe touch scanner for capturing 3D data points to facilitate reverse engineering or data acquisition from existing components.

The Engine Lab contains a variety of internal combustion engines installed on dynamometer stands that can be used for studies of diesel and spark-ignition engines. The facilities include a chassis dynamometer and instrumentation for evaluating engine performance, measuring exhaust gas emissions, and measuring noise. Studies can be conducted using a variety of fuels.

The Fluid Dynamics/Thermal Science Lab contains equipment to illustrate the principles of fluid flow and heat transfer and to familiarize students with hydraulic machines, refrigeration cycles, and their instrumentation. The lab also contains a subsonic wind tunnel equipped with an axial flow fan with adjustable pitch blades to study aerodynamics. Research tools include modern nonintrusive flow measurement systems.

The Instrumentation Lab contains six computer stations equipped with state-of-the-art, PC-based data acquisition hardware and software systems. A variety of transducers and test experiments for making mechanical, thermal, and fluid measurements are part of this lab.

The Materials Laboratory contains equipment for metallography and optical examination of the microstructure of materials as well as instruments for mechanical properties characterization including tension, compression, hardness, and impact testing. The Materials Laboratory also has a tube furnace for heat treating and a specialized bell-jar furnace for pour casting and suction casting of metallic glasses and novel alloy compositions.

The Robotic Systems Laboratory is an interdisciplinary laboratory specializing in the design, control, and teleoperation of highly capable robotic systems for scientific discovery, technology validation, and engineering education. Laboratory students develop and operate systems that include spacecraft, underwater robots, aircraft, and land rovers. These projects serve as ideal testbeds for learning and conducting research in mechatronic system design, guidance and navigation, command and control systems, and human-machine interfaces.

The Vibrations and Control Systems Lab is equipped with two flexible test systems. One is capable of single or multi DOF modes, free or forced motion, and adjustable damping. The other is an inverted pendulum. Both systems can be controlled by a wide variety of control algorithms and are fully computer connected for data acquisition and control.
