Modal Analysis of the Frame Structure of a Hybrid Electric City Bus

摘要

The vibration problem of the vehicle in the running process due to excitation by various external loads and the transmission part of the resulting, in this paper, based on the theory of modal analysis, the natural frequencies and natural modes of a hybrid electric city bus frame are solved. The result is compared with the external disturbance frequency is shown that the resonance phenomenon will not occur during the normal running of the vehicle. This study provides a theoretical basis for the structural design and optimization of the frame.
