Research on Tyre Vertical Load and Rutting Evolution of a Virtual Track Train
摘要
The virtual track train is a kind of new medium capacity rail transit vehicle. In this paper, the main architecture form of the virtual track train is introduced. And the three modules with six axles virtual track train is selected as research object. Its dynamic model is created by using SIMPACK software, and the influence of the road surface irregularity and running speed on the tyre vertical load is studied. At the same time, the finite element model of the asphalt pavement is created by using ABAQUS software. The tyre vertical load from dynamic calculation is applied to the finite element model of asphalt pavement as an external load, so as to study the relationship between rutting evolution and train running speed.
