摘要
本文采用国内现行列车速度构架振动的实测资料和国外高速列车轮对横向荷载测试资料，根据随机振动能量理论［１］，用能量方差σ２作为控制条件，随机模拟出了高速列车构架人工蛇行波，并初步验证了以此波作为高速列车－桥梁时变系统激振源的正确性．
In this paper. by making use of the up-to-date vibration in our country andthose of wheelsets' lateral load of high-speed train in other country the artificial crawl wave of high speed train frame is simulated at random in thecontrol of energy deviation a: according to random vibration energy thesis.The artificial craw wave functioning as high speed train-bridge system exciting resource is tested and verified.
