列车-轨道时变系统横向振动能量随机分析方法
|
摘要
根据大量客、货车构架实测蛇行波及德国高速机车轮对横向摇摆力的测试资料 ,基于随机振动理论模拟出一般车速及高速构架人工蛇行波 ,分别以构架人工蛇行波及前苏联规律性的竖向不平顺函数为横向及竖向激振源 ,对列车 -轨道时变系统横向随机振动进行计算。计算结果与实测结果的接近验证了本文方法的可行有效性
Referring to the artificial seismic wave theory, the artificial bogie crawl waves at different vehicle speeds (including the common speed and the high speed) are stochastically simulated on the basis of energy random analysis theory according to a great deal of spot test bogie crawl waves of the vehicles (including the locomotive, the passenger and freight car) and the wheelset lateral swaying force testing data by former Federal Republic of Germany. With the artificial bogie crawl waves as lateral vibraton source and the irregularity function presented by former Soviet Union as vertical vibraton source, the stochastic analysis results of space vibration for the train track time varying system can be obtained. The approximation of the numerical results to the spot test results demonstrates the feasibility and effectiveness of the presented method.
