摘要: 为了提高车辆-轨道耦合动力学系统可视化仿真的逼真度, 采用迹线法计算了车轮踏面接触轮廓面, 以平面方式表现轮轨动态接触关系, 钢轨以梁的形式参与振动, 通过实时建立具有一定垂向、横向和扭转振动形态的钢轨模型来模拟钢轨的振动行为。仿真结果表明, 在保证优良的实时性的同时, 可以清晰地观察轮轨接触点的变化情况, 免去了在复杂的三维场景中变换视点的操作, 使轮轨动态接触关系更简洁, 通过实时创建钢轨模型, 使钢轨振动行为的模拟更逼真。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.
