基于多工况的纯电巡逻车车架优化设计
Optimization design of an electric patrol vehicle frame based on multi-operating conditions
摘要
Abstract
In order to improve the endurance of the electric patrol vehicle,thereby enabling civil servants to perform their duties more effectively,the 4-seat pure electric patrol vehicle frame was taken as the analysis object,and its finite element model was established by HyperMesh software.Under full load condition,the performance of the frame body under vertical,braking and steering conditions was analyzed.According to the analysis results,the stiffness and strength of the main part of the frame are excessive.Due to the large number of components in this frame,it is inefficient and impractical to determine the impact of key components on the overall frame performance.Therefore,sensitivity analysis was used to obtain the sensitivity functions of mass,first-order mode and braking conditions respectively.The relative sensitivity of modal and braking conditions to mass was calculated respectively,and the components with smaller absolute value of relative sensitivity were selected.These components were used as design variables to optimize the size of the frame.In order to ensure the rationality of the optimized structure,the total weight of the frame was reduced by 22.1 kg,which demonstrated a significant lightweight effect.关键词
