摘要为了及时掌握列车反复荷载作用下的轨道几何形位状态,各国铁路管理部门都采用了现代轨检车和计算机处理技术来监测其变化情况,并制定了相应的评价标准。 - By means of trigonometrical progression method and the mainline track spectrum , the sample function of the chinese mainline railway track random geometric irregularity is simulated . with the data obtained from track geometry inspection car on qinhuangdao - shenyang special line for passenger transport and arma time series model , the sample function of high - speed railway track random geometric irregularity are simulated . based on existing literature , the artificial bogie crawl waves at various different speeds are randomly simulated
根据我国干线铁路轨道谱,采用三角级数法模拟出干线铁路和准高速铁路轨道不平顺的样本函数;根据秦沈客运专线高速试验段轨检车资料,采用arma时间序列模型模拟了高速铁路轨道不平顺随机样本函数;在既有研究资料的基础上模拟出各种速度客车构架人工蛇行波;用随机变量描述道床横向刚度,并进行了随机模拟;将振动理论和稳定理论结合建立系统的分析模型和运动方程;根据monte ? carlo法编制了车辆?轨道耦合系统随机振动分析程序,进行了无缝线路随机动力响应分析,通过试验对计算模型、计算方法进行了验证。
