To improve the body crashworthiness of a battery electric SUV under extreme conditions, the research employs a collision energy management method to conduct simulation under two side impact conditions of the China Insurance Automotive Safety Index (C-IASI) and truck. The body transmission path, load-bearing target definitions for critical structures, structural deformation and failure modes are compared and analyzed. Furthermore, the body structure is optimized targeting the extreme truck side impact condition. Simulation results and physical vehicle test results demonstrate that the body crashworthiness under extreme condition is significantly improved after optimization.

为提高某纯电SUV在极限工况下的车体耐撞性,基于碰撞能量管理方法,对该车型在中国保险汽车安全指数(C-IASI)侧面碰撞与载货汽车侧面碰撞两种工况下进行仿真,对比分析了车体传递路径、关键结构承载目标设定、结构变形与失效模式等,并针对载货汽车侧面碰撞极限工况进行车身结构优化,仿真与实车验证结果表明,优化后极限工况下的车体耐撞性显著提升。

为提高某纯电SUV在极限工况下的车体耐撞性,基于碰撞能量管理方法,对该车型在中国保险汽车安全指数(C-IASI)侧面碰撞与载货汽车侧面碰撞两种工况下进行仿真,对比分析了车体传递路径、关键结构承载目标设定、结构变形与失效模式等,并针对载货汽车侧面碰撞极限工况进行车身结构优化,仿真与实车验证结果表明,优化后极限工况下的车体耐撞性显著提升。

侧面碰撞  /  车身结构  /  耐撞性  /  碰撞能量管理

To improve the body crashworthiness of a battery electric SUV under extreme conditions, the research employs a collision energy management method to conduct simulation under two side impact conditions of the China Insurance Automotive Safety Index (C-IASI) and truck. The body transmission path, load-bearing target definitions for critical structures, structural deformation and failure modes are compared and analyzed. Furthermore, the body structure is optimized targeting the extreme truck side impact condition. Simulation results and physical vehicle test results demonstrate that the body crashworthiness under extreme condition is significantly improved after optimization.
