摘要
提出大腿的综合评价办法,通过MADYMO仿真软件建立了汽车正面碰撞乘员约束系统的仿真模型,并经过试验验证了模型的可靠性,对大腿伤害曲线进行了对标,在此对标好模型的基础上,分别从IP位置、乘员下肢偏置角度、小腿与地板的夹角这3方面对大腿伤害进行研究。结果表明:在符合人机工程学的同时,IP位置位于乘员膝部时队成员的伤害影响最小;乘员下肢偏置角度为12°为最佳位置;降低小腿与地板的夹角可不同程度地降低乘员大腿的伤害。因此,当汽车发生碰撞时,提前调整有关参数能够有效降低乘员的损伤风险,对汽车主动安全的研发与设计具有重要意义。
The comprehensive evaluation method of thigh is proposed.The simulation model of the car frontal col lision occupant restraint system is established by MADYMO simulation software.The reliability of the model is verified by experiments,and the thigh injury curve is benchmarked.In the above,the thigh injury was studied from the IP position’the angle of the occupant’s lower limb offset’and the angle between the lower leg and the floor.The results show that:ergonomics,while the IP position is located in the occupant,s knee,the team mem bers have the least impact;the occupant^s lower limb bias angle is 12°.For the best position;reducing the angle between the calf and the floor can reduce the damage of the occupant,s thigh to varying degrees.Therefore,when the car collides,adjusting the relevant parameter parameters in advance can effectively reduce the risk of occupant injury,which is of geat significance for the research and development of the car'active safety.
