摘要
应用经可靠性验证的中国50百分位成年男性下肢生物力学有限元模型进行了汽车侧面低速碰撞仿真研究,分析了不同碰撞速度以及不同汽车前部结构对行人下肢生物力学响应和损伤风险的影响。结果表明,碰撞速度对行人下肢生物力学响应具有显著影响;且填充保险杠缓冲泡沫尤其是上窄下宽梯形结构泡沫、或适当降低保险杠高度均有利于改善汽车对行人下肢的友好性。
With lower extremity biomechanics FE model of 50 percentile Chinese adult male,simulations on vehicles- pedestrain crash are conducted at low speed lateral loading to analyze the influence ofdifferent impact speeds and front- end structures on biomechanics response and injury risk of pedestrain lower extremity.The results demonstrate that the impact speed of vehicle has significant effects on the biomechanics response,and filling bumper buffer foamespecially trapezoidal structure buffer foam or decreasing the bumper height can improve the safety of cars to pedestrian lower extremity.
