摘　　要：根据国家标准《防止汽车转向机构对驾驶员伤害的规定》,人体模块以 2 4.1km/ h～ 2 5 .3 km/ h的速度水平撞击转向盘时 ,作用在转向盘上的水平力不得大于 1112 3 N。本文按国家标准建立了人体模块与某车型的转向机构有限元模型 ,并对试验过程进行数值模拟分析 ,仿真结果与试验结果吻合。因此 。According to the Chinese national standard about protecting car driver from being injured by motor vehicle steering mechanism, when a human model crashes to a steering wheel at the speed of 24.1~25.3 km/h, the force acted on the steering wheel should be less than 11123 N. In this paper, a steering system and human model are established by finite element method. The whole course of crash was simulated. Test results show that the analysis and simulation techniques are successful and the method of numerical simulation is effective in improving automotive passive safety scheme.
