| Abstract: | With the artificial bogie crawl waves as lateral vibrating source and the irregularity function presented by former Soviet Union as vertical vibrating source, results of stochastic analysis on space vibration of the quasi high speed train track time varying system are obtained. The time history dynamic response curves of the sleepers space vibration, which are very close to that of spot testing data are found for the first time. The maximum values of these computational data are all in the ranges of maximum testing data at home and abroad. |
