欧盟自2011年1月份新增RCAR（汽车修理研究协会）保险杠低速碰撞的测试评估。为了解新增RCAR测试将如何影响保险等级的评估，本文根据RCAR保险杠低速碰撞试验及评价方法，以及低速碰撞车辆的设计思路和方法，用Oasys和Hypwork等模拟软件，对某SUV实车进行了仿真分析。结果为：该实车防撞梁本体的刚度差，且防撞梁和保险杠之间没有支撑物，因此不足以提供碰撞过程中的支撑力：该实车防撞梁的中心线高度与壁障可变形部分的中心线高度没有在同一条直线上，故车体损坏件较多，降低了该车的保险等级。提出了一些改善汽车被动安全的措施。

Bumper low-speed structural crash tests proposed by Research Council for Automobile Repairs (RCAR) were added to the official insurance level assessment programs by European Commission in January 2011. Bumper low-speed crash was simulated for a real sports utility vehicle (SUV) to analyze the effects of the new RCAR tests on the insurance rating evaluation adopting Oasys and Hypwork software tools, the test and evaluation methods of RCAR, and the design concept for vehicles in low speed crash. The results show low stiffness of the bumper beam with the absence of underpins between the bumper and the bumper beam resulting in poor support in the crash. Barrier's deformable section center line does not align with the bumper beam center line, which induces heavy damage and reduces the vehicle insurance rating. Some measures are given to perfect vehicle passive security.
