摘　　要：基于立姿人体模型以及乘客与轿厢底面的接触模型,完成了乘客-轿厢-缓冲器耦合模型的建立.引入人体各生理环节的损伤评价指标,对人体各部位在蹲底事故中所遭受冲击损伤进行评估.仿真结果表明,人体与轿厢直接接触的足部受到的冲击力最大,从足部到头部,各生理环节受到的冲击力逐渐变小.由于人体各生理环节承受冲击的耐限不同,在蹲底事故中大腿比较容易受伤.针对不同的蹲底速度、缓冲器参数以及鞋子硬度进行仿真,分析了这些因素在蹲底事故中对乘客冲击响应的影响.Biodynamic response of lumped parameter passenger-car-buffer interaction model coupled with simplified model of ground-foot was investigated. The numerical results revealed the characteristics of hu- man response to buffer strike motion. The part in direct contact with the structure like the foot suffers greater impact than other parts like the head. Injury criteria were also summarized to facilitate injury assessment according to the tolerance levels for axial loading of the human body, and it is concluded that the upper leg is much more vulnerable. The influence of elevator velocity, buffer characteristics and shoes were investigated as well.
