摘要
Abstract Power battery is an important part of electric bus. With the standardization of electric bus manufacturing, a standardized power battery has been formed. In this paper, the standardized power battery box chassis of electric bus is taken as the research object, and the finite element analysis method is used to simulate its mechanical characteristics. The results show that the maximum equivalent stress of the battery box chassis is 50.7mpa, which is far less than the allowable stress value of the material. The first six modes have a vibration frequency range of 36.76-246.12Hz, and the frequency distribution of the modes is relatively scattered.
