护栏碰撞的汽车模型标准化

目前在我国公路护栏检验的实车碰撞试验中,所使用的车辆选择原则较为粗略,只规定了车辆车重、重心等大致参数,所用车辆较为随意,并不能代表我国的主流车型,很大程度上会影响实车碰撞实验结果的准确性和可重复性.论文通过我国汽车保有量调查和分析,得出主流车型表,并利用逆向建模建立了目前保有量最大的车辆模型,为护栏的检验和研发提供了计算模型.

The Car Model Standardization in Guardrail Collision

At present, in the real car collision test for inspection of highway guardrail, we roughly select cars with its weight and centre of gravity, these cars can not represent the mainstream car type in our country, which will largely affect the accuracy and repeatability of real car collision results. We get the mainstream car type through the survey and analysis of the automobile in our country, and establish a car model with the largest car ownership through reverse engineering, also provide the calculation model for test, research and development of guardrail.
