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]. |
