Wooram Park is an associate professor of instruction in the Department of Mechanical Engineering at University of Texas at Dallas. Prior to joining UT Dallas in 2011, he was a postdoctoral fellow in Mechanical Engineering at Johns Hopkins University. He received his PhD degree in Mechanical Engineering from Johns Hopkins University in 2008. He also received the B.S.E. and M.S.E. degrees in Mechanical Engineering from Seoul National University, Seoul, Korea, in 1999 and 2003, respectively. He received the IEEE Transactions on Automation Science and Engineering Best Paper Award in 2015. He is a member of IEEE and ASME.
He is interested in education of engineering students with the emphasis on robotics and control systems. His research mainly concerns various theoretic problems in robotics such as path planning and kinematic modeling.
Abstract
This paper documents our effort to improve learning experience for students in mechanical vibration class by designing and developing a teaching apparatus. In general, an undergraduate level vibration class covers various vibration phenomena including free vibrations and forced vibrations. Since the vibratory dynamic system generally consists of a mass, a spring, and a damper and its governing equation is a second order differential equation, most lecture contents are developed to provide the analytic analysis using challenging mathematical approaches. Even though this theoretic approach provides academic and practical advantages for students, many students struggle to achieve intuitive understanding on how real vibratory systems behave. It is even more challenging to connect the analysis results and the physical behaviors of vibration systems. To help these students, we designed and developed a teaching apparatus through a capstone design project in the department. In the one-year design project, a group of seniors designed a rotational vibratory system with springs and a torsional damper. Moment of inertia, stiffness and damping are all adjustable so the user can test various vibration conditions such as under-damping, over-damping, critical damping as well as forced vibrations. The system was also designed to be affordable. The apparatus was demonstrated in the class and was evaluated in a student survey. To promote the adoption of the proposed apparatus, the list of components is provided in this paper.
