| Abstract: | Using the flange clearance and the wheel/rail dynamical clearance, a method is presented to calculate the lateral impact force acting on the guardrail. Based on a vehicle/turnout spatial coupled vibration model, the dynamic responses of the guardrail are calculated by simulation when the vehicle passing through the No. 12 speedraised movablepoint simple turnout. |
