一、前言铁道车辆在通过曲线时所产生的横向压力和轮缘力,是一个与车辆脱轨、钢轨破坏、轮缘和钢轨的磨耗等相关联的极其重要的物理量。关于这些力的计算理论,虽然早就展开了,但是由于都是基于假定,所以都有缺乏普通性和实用性的缺陷。因此,笔者试以考虑作用于轮轨间的蠕滑力的非线性而进行理论分析,提出了对横向压力与轮缘力的新的计算方法。认为这种方法是对车辆静态曲线通过性能定量评价的有效手段。另外,本文是以相当于二轴转向架车辆 I. INTRODUCTION The lateral pressure and rim force generated by railway vehicles as they pass through the curve are an extremely important physical quantity that is associated with derailment of vehicles, destruction of rails, wear of rims and rails, and the like. Although the calculation theory of these forces has long been carried out, they all lack the defects of commonality and practicability because they are all based on assumptions. Therefore, I try to consider the role of non-linearity between the wheel-rail creep and theoretical analysis, put forward a new method of calculation of lateral pressure and rim force. It is considered that this method is an effective method to quantitatively evaluate the static curve passing performance of vehicles. In addition, this article is equivalent to a two-axle bogie vehicle
