Impacting Analysis on the Coupler and Buffer of a Subway Vehicle for the Shunting Operations
After the general model of shunting operation was established, non-linear damping force was imported into ADAMS by means of spline function. Under the same coupling speed, the relationship between 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 number difference of moving vehicles and static vehicles between the coupling interface was more, the maximum impacting force was smaller, and the buffer stroke was shorter.
