Improvement of Collision Safety Design for Electric Bus
This article is based on the pure electric power upgrade of a traditional fuel powered bus.The engine,gearbox,fuel tank,supply and return pipelines,exhaust system,and some transmission systems of the traditional fuel powered vehicle are updated to power components such as electric motors,reducers,high-voltage battery packs,and high-voltage wiring harnesses of the new pure electric vehicle.The impact of the changes in the above parts on collision safety is evaluated and CAE analysis is carried out.The problems identified during the analysis process are analyzed for their causes,scheme improvements,and CAE verification,so that the structural collision safety of the new electric bus meets the design requirements.
