Table 2 Boundary conditions for the collision numerical calculation

From: Research on the Influence of Multiple Parameters on the Responses of a B-type Subway Train

Collision Scenario Item Boundary condition
1 Collision mass 1 The weight of the Tc car is 34.08 t, the weight of the Mp/M car is 36.26 t, and the total weight of the six-car marshaling train is 213.2 t.
Collision velocity 25 km/h
Wheel-rail friction The wheel/rail friction coefficient is set as 0.008 [19].
2 Collision mass 2 (work order plus six persons standing per square meter) The weight of the Tc car is 46.56 t, the weight of the Mp/M car is 50.24 t, and the total weight of the six-car marshaling train is 294.08 t.
Collision velocity 15 km/h
Wheel-rail friction The wheel/rail friction coefficient is set as 0.008 [19].
