Dr. Yucheng Liu is the Jack Hatcher Chair Professor in the Department of Mechanical Engineering (ME) at Mississippi State University (MSU) and he currently serves as Graduate Coordinator in that department. Prior to joining MSU in 2014, Dr. Liu was the Assistant Professor of the ME Department at the University of Louisiana at Lafayette (UL Lafayette). Dr. Liu received his PhD degree from the University of Louisville in 2005 and Bachelor’s Degree from the Hefei University of Technology in 1997, both in Mechanical Engineering. Dr. Liu’s research has historically focused on the areas of multiscale material modeling and simulation, high strain rate performance of materials, vehicle systems design and analysis, and hydropower and wave energy technology. His current research interests and activities center on gaining a better understanding of the process-structure-property-performance relations of structural materials through advanced multiscale theoretical framework and integrated computational and experimental methods. To date, Dr. Liu has published about 200 peer reviewed publications, including more than 100 peer reviewed journal articles. He has been the PI and co-PI for over 40 research projects funded by NSF, DOD, DOE, NASA, FAA, Louisiana Board of Regents, and industry with the total amount of $8.7M. Dr. Liu has served as a panelist or a reviewer for several NSF, DOD, NASA, and DOE programs. Dr. Liu is a Professional Engineer registered in Ohio State and holds active membership in ASME, SAE, AAAS, and ASEE. Dr. Liu received the Junior Faculty Researcher of the Year of the College of Engineering at UL Lafayette in 2013, the Outstanding Senior Faculty Research Award from the ME Department in 2016, and MSU Faculty Research Award in 2018. Dr. Liu was named to the Jack Hatcher Chair in Engineering Entrepreneurship in 2018, and promoted to Full Professor in 2019. He was elected to ASME Fellow in 2017 and SAE Fellow in 2019 and holds active membership in ASEE and AAAS.

In this paper, two vibration systems designed and prototyped by mechanical engineering students at Mississippi State University are demonstrated at first. Those systems would help students to better understand damping effects and fluid viscous damper in a vibration system and this paper explains how the students applied knowledge learned from their vibration class to develop those systems and how to use the developed system to demonstrate vibration phenomena taught in the class. After that, evaluation results obtained from the Fall 2018 vibration class are presented and discussed. From the results, it can be confirmed that the implementation of the vibration system design into the class helped the students to develop their problem solving and teamwork skills and enabled the teacher to achieve the goals of that course. The Fall 2018 course evaluation results are clearly better than the results collected from Fall 2017 class, which indicates the improvement of teaching effectiveness and quality in that course. It is expected that the vibration course will continue to improve with more student designed vibration apparatus being implemented into the curriculum.
