论文摘要
随着地铁的发展以及对环保运输的紧迫需求，越来越多的人乘坐地铁旅行。近几十年来，关于火车上的乘客被动安全的问题受到了广泛的关注。在这项研究中，研究了地铁中一名常任乘客的头部受伤。在数字上设置了三种不同站立乘客姿势的MADYMO模型，定义为基线场景。具有不同姿势的乘客的HIC15值通过系统的参数研究获得。分析了各种情况的损伤数值模拟结果，分析了不同的摩擦系数，碰撞加速度，站立角度，水平扶手高度和环形扶手高度。结果表明，水平扶手在三种不同的站立乘客姿势中提供了更好的保护。在三种不同的情况下，不同的摩擦系数和站立角度对乘客的头部受伤产生了巨大影响。扶手高度对具有不同站立姿势的乘客的头部受伤也有一些影响，因此在设计地铁的内部布局时有必要考虑。这项研究可能为地铁的安全设计提供指导，并为站立地铁乘客提供一些建议。
With the development of the subway and the pressing demand of environmentally friendly transportation, more and more people travel by subway. In recent decades, the issues about passenger passive safety on the train have received extensive attention. In this research, the head injury of a standing passenger in the subway is investigated. Three MADYMO models of the different standing passenger postures, defined as baseline scenarios, are numerically set up. HIC15 values of passengers with different postures are gained by systematic parametric studies. The injury numerical simulation results of various scenarios with different friction coefficients, collision acceleration, standing angle, horizontal handrail height, and ring handrail height are analyzed. Results show that the horizontal handrail provides better protection in the three different standing passenger postures. Different friction coefficients and the standing angle have great impact on the head injuries of passengers in three different scenarios. The handrail height also has some effects on head injury of passengers with different standing postures, so it is necessary to be considered when designing the interior layout of the subway. This study may provide guidance for the safety design of the subway and some advices for standing subway passengers.
