摘要： 设计了一种偏置可变形壁障碰撞(ODB) 台车试验，以有效代替整车偏置碰撞试验。针对某款
长安乘用车，用Madymo 模拟软件，建立该车型驾驶员侧约束系统的计算机辅助工程(CAE) 仿真模型。
完成与整车64 km/h 的40% ODB 试验的对标，模拟了Hybrid Ⅲ型50 百分位假人在试验中的伤害参
数。同时考虑了台车的初始固定偏转角度和台车加速度两个变量，用CAE 仿真分析，确定台车车身设
置最优方案与整车试验对比。结果表明：对于头部、胸部等关键部位的伤害曲线，该台车试验方法与
整车试验相似度大于80%。从而，提供了一种用台车试验代替整车偏置碰撞的新方法。

Abstract: A kind of offset sled tests was designed to resemble whole-vehicle ODB (offset deformable barrier)
crash tests. A CAE (computer aided engineering) model was built by using MADYMO software for the driver side
restraint system of a Chang’an Motor’s car. The model was verified to simulate vehicle crash tests with 40% ODB
at a speed of 64 km/h. The injury parameters of the Hybrid Ⅲ 50th dummy were simulated and analyzed. Two
variables, the initial fixed rotation angle of sled and the sled acceleration curve, were optimized and determined
by using the CAE analysis in comparison with vehicle tests. The results show that the injury curves from the
occupant’s head and chest in the sled tests and from the vehicle tests are close each other in the rate of more
than 80%. Therefore, the designed sled test set up provides a new method to replace the whole vehicle crash tests in OBD.

Key words: vehicle crash safety, offset deformable barrier(ODB), sled tests, restrain systems, MADYMOsoftware
