摘　　要：《汽车侧面碰撞的乘员保护》标准(GB20071-2006)中明确规定,所有M1类车型和N1类车型,都必须满足侧碰的强制性规定。汽车侧面碰撞计算机仿真分析是汽车碰撞安全性研究的重要试验方法之一,而移动变形壁障模型是开展该试验的基本工具。按照法规中对移动变形壁障性能的要求及验证试验的方法,建立了移动变形壁障的有限元模型,并进行验证试验的仿真,确定模型的正确性。GB20071-2006 Occupant Protection of Side Impact is a compulsive and executable standard that all M1 and Nl style automobile must obey to Simulation for car side impact is one of important test methods to study vehicle impact safety. And model of moving deformable barrier is the basic tools of the test. According to the requirements for the performance of moving deformable barrier and test verification method in this regulation,the finite element model of moving deformable barrier is built and the simulating test is carried out in order to verify the correctness of the model.
