摘要

建立了2列相同编组B型地铁列车纵向冲击时的一维纵向动力学模型，并对车端吸能元件进行了建模仿真（包括可逆吸能元件如车钩橡胶缓冲器、不可逆吸能元件如车钩压溃管和车端防爬器）。为满足列车碰撞多级吸能需求，对车端不可逆吸能元件（压溃管）的参数进行优化设计，对比分析了其采用恒定力值、阶梯力值、渐变力值时的各断面吸能情况。结果表明，可变力值吸能元件能够更好地满足列车在不同碰撞速度下的吸能需求，更有利于能量吸收在不同断面中的均匀分布，从而更好地解决车端空间有限与吸能元件行程不足的矛盾，其中渐变力值元件吸能表现优于阶梯力值方案。相关计算结论可为系列化标准地铁列车钩缓系统吸能元件压溃管参数配置提供参考。

Abstract

A 1-D longitudinal dynamics model was built with two type B metro trains of the same consist under longitudinal impact with each other

and the energy absorbing elements at the end of cars were modelled and simulated (including the reversible energy absorbing elements such as the rubber draft gear and irreversible ones such as the collapsible tube and anti-creeper). The parameters for the irreversible energy absorbing elements (collapsible tube) at the end of cars were optimized

for the sake of meeting multi-stage energy absorbing in train collisions

and comparative analysis was conducted on energy absorption in sections under the scenarios of a constant resistance force pattern

multistage resistance force pattern

and gradient resistance force pattern. According to the results

the variable resistance force pattern gives the energy absorbing element the best performance to meet the energy absorbing requirement at different speeds in collisions

to the benefit of uniform distribution of energy absorbing across sections

as the best solution to tackle the contradiction between a limited space between cars and insufficient energy absorbing stroke. Furthermore

the gradient resistance force pattern presents a better energy absorbing performance than the multistage resistance force pattern. The simulation results may serve as a reference in the parameter configuration of the energy absorbing elements in the coupler and draft gear system

especially the collapsible tube.
