摘要
建立了冲击车辆数学模型和动力学方程,运用ADAMS对不同编组调车作业进行了模拟,分析了各冲击分界面的冲击力之间的关系。对四种调车作业最大冲击力进行了比较,得出动车编组数多于静车编组数时,其最大冲击力最小。研究发现,最大冲击力发生在运动车辆和静止车辆的连接位置,分界面的冲击力只与分界面两侧的车辆有关,而与其它车辆无关。
The crashing vehicle model and the equations of dynamics are established,in which the stiffness and damping of hook and fluid elastic buffer of vehicle are considered. The software of ADAMS/s used for simulating the different marshalling vehicle that will be connected. The relationship between crashing force in the different crashing plane is analyzed. The maximum force produced in four marshalling vehicle is compared and analyzed. It is found that the maximum crashing force occur in the connecting position of the moving vehicle and static vehicle. The crashing force is only related with both side vehicles of the crashing interface.
