摘　　要：为同时满足配置麦弗逊和双叉臂前悬架车型的小偏置碰撞性能要求,针对麦弗逊和双叉臂前悬架在正面25%偏置碰撞工况中的变形模式及结果差异进行原因分析,通过增加门槛前端吸能块、弱化前指梁和A柱前端、设置门洞前部缓冲区域等措施对该车型进行了结构优化,并应用LS-DYNA仿真、实车试验验证了安全策略和优化措施的有效性,试验中车辆结构等级评定为优秀。To meet the small offset barrier crash performance requirements of both McPherson and double wishbone front suspension system,this paper analyzes the cause of deformation pattern and discrepancy of results in 25%offset collision condition of both McPherson and double wishbone front suspension.The vehicle is optimized structurally by taking measures such as adding energy absorption zone at the front end of doorsill,wreaking the front beam and A-pillar front segment,and setting the buffer zone of the front end of door.Effectiveness of these safety strategies and optimization measures have been verified by LS-DYNA simulation and real vehicle test,in which the vehicle structure grade is rated as excellent.
