碩士 === 國立臺灣大學 === 機械工程學研究所 === 104 === Weight reduction of gearbox is an effective approach for electrical vehicles to extend their driving range. Nevertheless, lightening will result in reduction of the stiffness of structure, which makes resonance excited that drops off the efficiency of driveline, life time of parts, and passengers comfort. Therefore, this thesis brings up a brand new method, which optimize the structure of gearbox in electric vehicles. By using Abaqus(FEA software) to build the EV car driveline model. The accuracy of the driveline model is verified by the experimental modal analysis. This design strategy also includes the Topology optimization, and it can achieve the design goals in strength, stiffness, and natural frequency simultaneously so that we can avoid resonance to improve the driveline efficiency.
