摘　　要：【目的】为解决目前重载钢轨大机打磨作业过程中存在的依靠经验选择打磨模式和打磨结果无法预测的问题。【方法】以GMC-96X大型钢轨打磨列车作为研究对象,通过MATLAB数值模拟,研究不同打磨模式的作用效果;并且结合打磨列车砂轮分布形式,建立钢轨打磨基本模式库,提出了一种基于打磨量曲线的重载铁路钢轨打磨模式设计方法。【结果】现场试验结果表明:采用该方法设计的打磨模式包含了打磨列车各个砂轮的摆布角度,可直接输入到打磨列车控制系统,更为贴合实际应用;并且通过打磨前钢轨实测廓形、理论打磨后钢轨廓形和实际打磨后钢轨廓形三者的对比,验证了该方法的可靠性。【结论】该打磨模式设计方法实现了重载铁路钢轨打磨模式的自动生成和轨头廓形的精确修理。【Objective】To solve the problems of selecting grinding modes based on experience and unpredictable grinding results in the current grinding operation by rail grinding trains.【Method】This paper takes the GMC-96X rail grinding train as the research object,to research the effects of different grinding modes by means of numerical simulation through MATLAB.By combining the distribution of grinding wheels in the grinding train,the basic model library of rail grinding is established,and a design method of rail grinding mode based on the grinding amount curve is proposed,which realizes the automatic generation of grinding mode and the precise repair of the rail head profile.【Result】The field test results show that the grinding mode designed by this method includes all angles of each grinding wheel of the grinding train,that can be directly input to the control system,which is more suitable for practical applications.【Conclusion】By comparing the measured rail profile before grinding,after theoretical grinding,and after actual grinding,the reliability of the method is verified.
