摘要
针对西平线跨度为80 m的钢—混凝土组合桥的轨道不平顺问题,采用德国低干扰谱转换的时域不平顺样本及美国五级谱分别对客车、货车进行动力仿真分析,研究结果表明:列车行驶的平稳性都达到了标准.
Contraposing the problem railway not flat of eighty meters length combination truss bridges in Xian to Pingliang railway lines ,We take low jammer chart transition space -time of the wailway not flat from Germany and five level chart from America to analyse carriage and truck separately , and the study result shows that all the trains run calmly and reach the standard of good.
