碩士 === 國立臺灣大學 === 機械工程學研究所 === 100 === The in-wheel motor electric vehicle has a large car room space allocation, as well as more high-efficiency and energy saving advantages. It is an important direction in the development of vehicle electrification. The main problem unsprung mass is too large, resulting in poor handling and ride comfort. The research will apply the dynamic vibration absorbers theory through the literature of the in-wheel motors, mechanical design concept and the parallel suspension system to build the full vehicle CAE model through ADAMS View analysis software. More realistic simulation of the in-wheel motors agencies and the suspension system, so you can get a more accurate analysis of the situation. The full vehicle model can provide more, including the steering and six dimensions (forward, lateral, vertical, roll, pitch, yaw) of the information than the fourth car or three-dimensional motion of the half car model. To establish the full vehicle CAE model is to connecting the in-wheel motors from the vehicle through the double A-arm suspension. The suspension coefficients spreadsheet tool developed in this study in order to provide a set of dynamic simulation analysis of the full vehicle design parameters. Finally, by the sensitivity in the test conditions to make an analysis to identify the dynamic characteristics of orientation of the main suspension and the second suspension spring and damping coefficients of adjustment direction, I look forward to this study, the reference value in-wheel motor vehicle design.
