Simulation of Vehicle's Inspectation on the Rail based on TBDS Track and Vehicle Coupling Model
Jiang Weng， Hu Yongsheng, Zhan Chunbo
Abstract：In this paper, the significance of inspecting the wheel/rail force when the vehicle is running on the rail is presented briefly.Taking this inspection of wheel tread flat as an example, this paper discusses how to arrange strain gauge on the rail, then simulates the process of wheel tread inspection on the rail based on track TBDS (Timoshenko beam on discrete) and vehicle coupling model.
Key words：railway vehicle； inspection on the rail； wheel tread flat
