Abstract

Abstract

In order to improve the visual simulation fidelity of wheel-rail coupling dynamics system, wheel contact profile was calculated by using trace-line method, the dynamic contact relation of wheel-rail was displayed by using planar way, rail was regareed as beam to participate in vibration, and rail vibration behavior was simulated through building real-time rail model with vertical, lateral and torsional shapes.Simulation result shows that the simulation system is feasible, the real-time motion regulation of wheel-rail contact point is clearly observed, intricate visual point transformation is avoided in 3-D scene, wheel-rail contact relation is more succinct, and the simulation of rail vibration behavior is more realistic by building real-time rail model.
