基于列车动力学和道岔动力学理论，建立可考虑整体道床12号交叉渡线道岔钢轨型面变化的列车道岔耦合动力学计算模型。用数值模拟方法分析动车组和货车以50 km/h侧向通过该交叉渡线道岔时的动力学特性。结果表明：动车组和货车通过时轮轨力、脱轨系数、减载率、轮轴横向力、车体振动响应有所不同，但均满足安全舒适要求。
基于列車動力學和道岔動力學理論，建立可攷慮整體道床12號交扠渡線道岔鋼軌型麵變化的列車道岔耦閤動力學計算模型。用數值模擬方法分析動車組和貨車以50 km/h側嚮通過該交扠渡線道岔時的動力學特性。結果錶明：動車組和貨車通過時輪軌力、脫軌繫數、減載率、輪軸橫嚮力、車體振動響應有所不同，但均滿足安全舒適要求。

Based on the theories of train dynamics and turnout dynamics, a dynamic model for a vehicle-turnout coupling system is established to address rail profile changes of No. 12 crossover turnout with solid bed. The dynamic characteristics of EMUS and freight car are analyzed with numerical simulation method when they pass through crossover turnout at the speed of 50 km/h. The results show that EMUS and freight car may differ in wheel-rail force, derailment coefficient, load reduction rate, axle lateral force, car body vibration response when passing through the turnout, but both meet the requirements for safety and comfort.
