Simulation Calculation of Lateral Impact Force Acting on Guard Rail while Passing Through Turnout Zone on the Side-Way

摘要: 利用轮缘槽和动态轮轨间隙量,给出了计算道岔护轨横向冲击力的方法。在车辆-道岔空间耦合振动模型的基础上,模拟计算出了车辆侧向通过12号单开提速道岔时护轨的冲击力响应情况。

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 speed-raised movable-point simple turnout.
