【摘要】：近年來,隨著我國汽車行業(yè)的迅猛發(fā)展,交通事故中行人的死亡率逐年增加,行人保護(hù)研究作為汽車安全的新興領(lǐng)域已經(jīng)引起了廣泛關(guān)注,為減少在交通事故中對行人的傷害,基于有限元方法,分別建立汽車前部結(jié)構(gòu)以及小腿沖擊器的有限元模型,并采用LS-DYNA軟件模擬人車碰撞過程,選取不同的泡沫密度進(jìn)行仿真模擬,并且與試驗進(jìn)行對比。結(jié)果表明,降低保險杠泡沫密度后,汽車前部結(jié)構(gòu)對行人的傷害明顯降低,該結(jié)論可為汽車前部保險杠的設(shè)計提供參考。
[Abstract]:In recent years, with the rapid development of automobile industry in China, pedestrian mortality in traffic accidents has increased year by year. As a new field of automobile safety, pedestrian protection research has attracted extensive attention. In order to reduce the damage to pedestrians in traffic accidents, the finite element models of the front structure of the vehicle and the crater of the shank are established based on the finite element method, and the collision process of the vehicle is simulated by LS-DYNA software. Different foam density is selected for simulation and compared with the experiment. The results show that the damage to pedestrian caused by the front structure of the vehicle is obviously reduced after reducing the foam density of bumper. The conclusion can provide reference for the design of front bumper.

【正文快照】： 1引言在汽車各項技術(shù)的發(fā)展過程中,人們一直比較注重車內(nèi)乘員的保護(hù),然而行人的碰撞保護(hù)研究卻沒有受到同等重視,相對于車內(nèi)乘員傷亡人數(shù)的逐年減少,車外行人傷亡比率反而逐年增加。作為現(xiàn)代汽車其安全系數(shù)不僅取決于發(fā)生碰撞時對車內(nèi)成員的保護(hù)是否到位,還要看它能否減輕對行，
