基于动态峰值力的客车骨架轻量化研究
Study on lightweight of bus frame based on dynamic peak force
摘要
Abstract
Aiming at the deficiency of the bus frame design optimization based on the static fore,the design optimization of the bus frame based on dynamic peak force is proposed.The dynamic model of the vehicle and the road model were established in this method,and the dynamic peak force of the frame was calculated.The finite element analysis and design optimization model of the frame were established based on dynamic peak force.One bus was taken as an example,the quality of the frame is reduced by 8.84％ percentage through the method of the bus frame design optimization based on dynamic peak force.The strength and stiffness of the frame after optimization meet the requirements.The results show that the method of the bus frame design optimization based on dynamic peak force is reliable.It can be directly applied to any vehicle and structure design optimization under any condition without specific consideration dynamic load coefficient of the experimental research under different working conditions.It also shorten the design time and save the development costs.关键词
