建立了车轮扁疤冲击作用下轮轨垂向振动系统的动力有限元模型，采用Ｎｅｗｍａｒｋ算法对扁疤冲击过程中轮轨力、轨脚弯曲应力、钢轨振动加速度与振动速度的平方值等钢轨振动特征量进行了数值仿真分析。本文内容为扁疤的定量测试提供了研究方法和理论依据。
The dynamic finite element model of the wheel-rail vertical vibration system under wheel flat-bladed impact was established. The Newmark algorithm was used to calculate the wheel-rail force, the rail-foot bending stress, the rail vibration acceleration and the square of the vibration velocity The characteristics of the numerical simulation. This article provides the research methods and theoretical basis for quantitative testing of flat scars.
