摘要
本文采用动态和蠕滑理论计算了轨道所受的导向力和冲角。在文章中考虑了轮轨踏面形状对钢轨受力的影响,论述了钢轨顶面的蠕滑力、蠕滑力矩和法向力的计算过程,并提出作用在外轨内侧导向力的计算方法。通过解动态方程组,得到了对曲线轨道钢轨侧磨分析所需要的导向力和冲角。
In the paper,the forces and attack angles acted on the high rail on the curved-track are calculated with the dynamic and creep theories.The effects of the configuration ofthe wheels and rails to the directive forces and attack angles are considered in the paper. Thepaper also describes the calculating process of the creep forces and the creep moments with Kalker′s theory and the normal forces acted on the rail top surfaces,and then puts forward amethod to analyse the directive forces acted on the gauge corner of high rail.By solving thedynamic differential equations with Runge-Kutta method,the directive force and attack angles are obtained for analysing the wear on the gauge corner of high rail on the curved-track.
