随着高速、重载铁路的发展,钢轨的承载能力以及工况参数对它的影响问题受到越来越多的专家学者的关注。本文着重讨论摩擦系数、轴重对轨头内弹塑性接触应力场的影响,横移量与摇头角的影响将不作详细讨论。研究得到,横移量是影响轨头内弹塑性接触应力场的最关键的工况参数,轴重的影响也是很大的,次之是摩擦系数,影响最小的是摇头角
With the development of high-speed and heavy-haul railroads, more and more experts and scholars pay more attention to the influence of rail carrying capacity and operating parameters on it. This article focuses on the influence of friction coefficient and axle load on the elasto-plastic contact stress field in the rail head. The effects of the amount of traverse and the moving angle will not be discussed in detail. It is found that the horizontal displacement is the most critical parameter affecting the elastic-plastic contact stress field in the rail head. The influence of shaft weight is also very large, followed by the friction coefficient, and the least influencing factor is the moving angle
