滑动接触时轮轨内的屈服点

Yield Point Produced in Rail and Wheel by Slipping Contact

通过大量数值计算,本文给出了滑动接触时接触体内(σ_i)_(max)的数值解,分析了其基本特征,并讨论了在轮轨滑动接触中的应用。本文的解为滑动接触时的屈服分析完成了一项基础工作。

A Large amont of numerical analysis is made to obtain the numerical solutions for(σ_i)_(max) produced in contact solid by slipping contact. The characters and the application to slipping rail/wheel contact of the (σ_i)_(max) are also discussed in this paper。These solutions can become one part of the basis for discussing yield point due to slipping contact.
