钢轨接触应力是造成钢轨轨头破损的一个重要因素,本文对钢轨接触应力的基本原理、计算方法及与轨头破损的关系作了介绍,分析了形成钢轨压溃、剥离、擦伤等病害的原因,提出了这些病害的有关计算公式及减少和予防这些危害的措施。本文还从钢轨接触应力角度出发,对我国铺设重载线路技术政策问题进行了探讨并提出了建议。
The contact stress of rail is an important factor that causes the rail head to be damaged. In this paper, the basic principle and calculation method of rail contact stress and the relationship with rail head damage are introduced. The formation of rail crushing, peeling, scratching and other diseases The reasons for this are as follows: The calculation formulas for these diseases and the measures to reduce and prevent these hazards are put forward. This article also from the rail contact stress point of view, the laying of heavy lines in our country technical policy issues were discussed and put forward suggestions.
