The compromise of theory, simulation and projects for mechanical component design courseDesign of mechanical components is one of core technical courses for mechanical engineering programwhich has been taught with tons of successful experiences and discussions. But recently, there aresome arguments about how to effectively execute this course. One argument was that theoreticalanalysis on different scenarios should be concentrated so that students had solid understanding aboutstress & strain calculations under combined loadings for machine element design. Another argumentwas that industrial engineers rarely runs the complicated theoretical calculation, but use the numericalsimulation for real component designs because FEA analysis is a common engineering tool now. Otherargument was that students could learn and explore the theories and skills as the design project drovestudents through the design process, during which, faculties served as a consultant to answer questionsand to provide some advice. We believe that theoretical analysis, numerical simulations and projectsare coherently related and inseparable for a mechanical components design course. The theoreticalanalysis is the base and foundation for mechanical components design. The numerical simulation suchas FEA analysis is numerical version of the fundamental theories. Conducting design project is theimplementation of the fundamental theories with the numerical simulation tools. In the recentlymodified mechanical components design course, we explored and discussed the fundamental theories,and then FEA analysis on components was used to replace some complicated theoretical analysis, andthe course included two design projects. The first project was a design check on a simple real device.This project was used to bridge the courses of strength of materials and the mechanical componentsdesign. They needed to run the loading analysis to obtain the maximum loading, then calculated thestress and conducted the design check against the design specifications. The second project was acommon mechanical device which contained several common machine elements: shafts, keys, bearings,gears, bolts, welding and cases. This papers will present the course contents, the execution plan &summary, experiences, feeling and some observations in teaching the mechanical components designcourse. Some feedback and discussions from students will be also presented and analyzed in thispaper.
