摘　　要：轨底坡的大小直接影响轮轨接触点的位置和轮轨力的作用方向及大小,适当地调整内外轨的轨底坡可改善轮轨之间的接触状况,使轮轨接触点发生变化而有利于轮对通过曲线。基于Simpack仿真软件,建立车辆系统动力学模型,设计不同曲线通过条件,分析了内外轨轨底坡相同和不同的情况下对轮轨接触行为及动力响应的影响。The size of the rail bottom slope directly affects the position of the wheel-rail contact point and the direction and magnitude of the wheel-rail force,and the appropriate adjustment of the rail slope of the inner and outer rails can improve the contact between the wheels and rails,so that the wheel-rail contact points change and are conducive to the wheelset passing curve.Based on the Simpack simulation software,the dynamics model of the vehicle system is established,and the passing conditions of different curves are designed,and the influence of the wheel-rail contact behavior and dynamic response on the wheel-rail contact behavior and dynamic response is ana⁃lyzed under the same and different conditions of the inner and outer rail bottom slopes.
