摘要
建立了地铁调车作业通用的冲击模型,在ADAMS中用样条函数模拟缓冲器的非线性阻尼力;研究在相同速度下,不同车辆编组和连挂面上最大冲击力以及缓冲器行程的关系;运用冲量方法和功能原理分析了相同速度、不同编组调车作业中车钩缓冲器的冲击力特性;得出车辆数一定、初始速度相同的条件下,连挂冲击面两侧动车和静车编组数相差越多,最大冲击力越小、缓冲器行程越短的结论。
After the general impact model of shunting operation was established,the non-linear damping force of buffer was simulated in ADAMS by spline function.Under the same coupling speed,the relationship among different shunting groups,the maximum impacting force and the buffer stroke was researched;the different impacting characteristics of the system were also analyzed under different shunting operations by means of the impulse transmission and kinetic theory method.In the condition of the same coupling speed and vehicles,the results are that the the more number difference of moving vehicles and static vehicles between the coupling interface,the smaller the maximum impacting force,and the shorter the buffer stroke.
