汽车碰撞驾驶员下肢行为响应及损伤分析
Behavioral response and injury analysis of lower extremity in automobile collision drivers
摘要
Abstract
The present standard dummy posture employed in automobile accident tests fails to consider the influence of the driver's instinctual emergency reaction on his own harm.To address this problem, we build an immersive driving simulator to obtain the changing characteristics of the driver's lower limb posture in the collision environment, then adopt the finite element method to simulate the collision scene,and finally compare the damage of various parts of the human body under the driver's emergency behavior through data analysis.Our results show when the driver's foot is on the accelerator pedal, he may suffer more severe head and thigh injuries;when his foot is on the brake pedal, the likelihood of him suffering chest compression is increased by 22.3％ compared with other attitude peaks.When the foot is on the brake pedal, the peak neck tension moment occurs and the viscosity index peak is reduced by 25％.When the driver's lower limb behavior varies, the degree of harm of each part of the body movement posture is considerably different, and the injury of each part is also notably different when compared to the standard posture.Our research may shed light onthe design of vehicle safety protection for Chinese and provide references for the improvement of related legislation on car crashes in China.关键词
