摘　　要：针对高速铁路钢轨打磨过程中存在砂轮磨损问题,深入研究了钢轨打磨过程和砂轮磨损检测,提出了采用自为基准的三点法对钢轨打磨砂轮的磨损进行间接测量,建立了三点法测量的数学模型,对三点法测量的影响因素和测量方案进行了仿真,并对仿真结果进行了分析,为测量小车的制作和测量方案的选取提供了依据。最后,对表示钢轨打磨前、后表面的两条正弦曲线进行了仿真测量,验证了三点法测量钢轨打磨砂轮磨损的可行性。仿真结果表明,该砂轮磨损检测方法是可行的,测量方案的稳定性明显。Aiming at the problem of high-speed railway rail grinding wheel wear, the rail grinding process and wheel wear detection were studied. Inspection on high-speed rail grinding wheel wear based on three-point method was presented. The mathematical model of the three-point method was created, influencing factors in three-point method of measuring process and measurement scheme was simulated. Simulation results were analyzed to provide a basis for the manufacture of the measurement car and the selection and measurement solutions. Last, two curves that signify the surfaces before and after rail gringing were measured by the simulation of three-point method to validate the feasibility of this method. The results indicate that the linearity testing is feasible and the stabilization of measuring method is obvious.
