随机不匀率
Establishing the dynamic performance simulation of high-speed train track random irregularity excitation model by taking the PSD ( Power Spectral Density), the change law of wheel/ rail vertical and horizontal force with curve radius value in less super high and super high state is obtained.
将德国高干扰谱用于高速动车动态性能仿真建立的轨道随机不平顺激扰模型,分析了欠超高和过超高状态下轮轨垂向力和横向力随曲线半径值变化规律。
