摘　　要：为了提高某轻型客车的偏置碰撞安全性,在外形保持不变以尽可能节约成本的前提下对车身进行改进。根据轻型客车大多采用半承载式车身,车架是主要的吸能部件的特点,把车架作为重点改进对象,采用台车试验和台车模拟相结合的方法,提高其正面偏置碰撞安全性能。In order to enhance the frontal offset crashworthiness of a light bus, modifications in body structure are conducted, keeping outer shape unchanged for reducing cost as far as possible. In view of that most of light buses adopt semi-monocoque construction and frame is the main energy-absorbing component, the focus of structural modification is on frame, the frontal offset crashworthiness of which is improved by combining sled test with sled simulation.

关 键 词：轻型客车 正面偏置碰撞 台车试验 台车模拟 安全性
