车轮轮缘接触应力与影响因素的研究

Research on Wheel-Flange Contact Stress and Influencing Factors

本文用赫兹理论计算了车轮轮缘接触应力，研究了车轮侧压力与轮缘根部圆弧半径对轮缘接触应力的影响，给出了各种计算工况下的数值解，为分析轮缘磨耗与车轮型面优化设计提供了理论依据。

This paper aims at calculating wheel-flange contact stress by using Hertzian theory, taking into account, the influence of wheel-flange lateral load and the radii of the root of wheel-flange. Numerical solution for various cases are given. The results will be useful to thereticall analysis of of wheel-flange wear and optimization tread configurations.
