正面小区域碰撞讨论

Small-area frontal-impact discuss for a vehicle

伴随着汽车技术的不断发展,人们对于汽车的安全性能也日益关注。在碰撞安全法规上,目前最严苛的当属美国公路安全保险协会IIHS提出的正面小区域碰撞。本文先介绍该碰撞测试的缘由、背景及测试工况,而后通过现有的实车测试报告及仿真试验数据对正面小区域碰撞过程中的碰撞力传递、能量传递、左侧B柱加速及车辆入侵量进行说明与分析,并总结出为什么在市多款车型在该碰撞测试下成绩不优秀及对车辆结构的改进提出方案。

With the continuous development of automobile technology, there are growing concerns for car safety performance is also.On the collision safety regulations, at present the most severe is the insurance institute for highway safety IIHS collision on the front of the small area is put forward.First introduced in this paper that the cause of the crash test, background and test conditions, and then through the existing real vehicle test report and in the process of simulation test data for small area positive collision collision force transfer, energy transfer, acceleration and the vehicle on the left side of the B column invasion by description and analysis, and why is summarized in the city, many models under the collision test result is not good, and the improvement of vehicle structure scheme is put forward.
