| Abstract: | As a city hub,pure electric technology can be used as a starting point to reduce urban environmental pollution and energy consumption.At present,the short driving distance is the main factor restricting the development of pure electric bus.The driving range can be increased by increasing the power of the power battery or lightening the whole vehicle.In the aspect of lightweight design,several lightweight materials such as high strength steel,aluminum alloy,magnesium alloy,engineering plastics and carbon fiber are compared and analyzed,and the most suitable aluminum alloy material is selected.Through theoretical calculation and design,and then verified by finite element analysis,the reasonable section and connection structure for body frame are designed.At the same time,through the cost evaluation and comparison in the whole life cycle,it is found that the cost of aluminum alloy body can be reduced. |
