Analyzing the dynamical performances of bogie and that of the whole vehicle based on multi-body dynamics, is the most effective method that examines the designed products. This article mainly uses SIMPACK software to simulate the dynamic performances of Qinghai-Tibet generator vehicle.
Differential equations are established about Qinghai-Tibet generator cars. And then multi-body dynamics models are set up in the article. In the case of five-grade-spectra of lines of American, the article analyse...
