摘要
随着汽车自动化技术发展,零重力座椅配置逐渐普及且颠覆了传统的乘员单一坐姿,对车辆乘员保护性能造成挑战.为评估零重力座椅配置对乘员保护性能的影响,本文对传统坐姿和零重力坐姿的乘员保护性能进行对比研究.然而,目前测试用假人均不能满足零重力座椅的多坐姿要求.基于能实现多坐姿要求的THUMS AM50人体模型,对比分析了传统坐姿和零重力坐姿下THUMS AM50的运动趋势以及损伤特征,同时研究了零重力座椅关键设计参数靠背角和坐垫倾角变化对THUMS50运动趋势的影响.结果表明传统坐姿乘员运动幅度较大,头部与胸部损伤较大;零重力坐姿乘员运动幅度较小,颈部与腰椎损伤较大;零重力座椅靠背角度增大会导致乘员发生下潜,坐垫倾角增加会减缓乘员下潜的发生.
With the development of automotive automation technology,the zero⁃gravity seat configuration is gradually being popularized,revolutionizing the traditional single seating posture and posing challenges to vehicle occupant protection performance.To evaluate the impact of the zero⁃gravity seat configuration on occupant protection performance,this paper compares the occupant protection performance between traditional and zero⁃gravity seating postures.However,current test dummies are unable to meet the multi⁃posture requirements of zero⁃gravity seats.Based on the THUMS AM50 human body model,which can accommodate multi⁃posture requirements,the motion trends and injury characteristics of THUMS AM50 in traditional and zero⁃gravity seating postures were compared and analyzed.Additionally,the influence of key design parameters of zero⁃gravity seats,such as the backrest angle and seat cushion inclination angle,on the THUMS AM50 motion trend was studied.The results show that occupants in the traditional seating posture experience larger motion amplitudes,with more significant head and chest injuries,while occupants in the zero⁃gravity seating posture exhibit smaller motion amplitudes but suffer more severe neck and lumbar injuries.Increasing the backrest angle of the zero⁃gravity seat can lead to occupant submarining,whereas increasing the seat cushion inclination angle can mitigate the occurrence of submarining.
