摘　　要：为了研究采煤机导向滑靴导向槽磨损规律,以某型号采煤机导向滑靴作为研究对象,基于Archard磨损模型建立了导向滑靴数学磨损模型,使用ABAQUS软件对导向滑靴与销排的相对滑动进行了仿真,分析了导向槽表面的磨损特性,探究了滑移距离对导向槽磨损的影响规律。研究结果表明:磨损初期导向滑靴与销排的实际接触面积逐渐增大,接触压力逐渐减小;采煤机运行100 km时导向滑靴的最大磨损深度为4.379 mm,对于耐磨层厚度为6 mm的导向滑靴,采煤机运行450 h后考虑对导向滑靴进行检修。In order to study the wear law of the guide groove of the shearer's guide slipper,taking a certain model of coal mining machine's guide slipper as the research object,a mathematical wear model of the guide slipper was established based on the Archard wear model.The relative sliding between the guide slipper and the pin row was simulated using ABAQUS software.The wear characteristics of the guide groove surface were analyzed.The influence of slip distance on the wear of the guide groove was explored.The research results indicate that in the early stage of wear,the actual contact area between the guide slipper and the pin row gradually increases,and the contact pressure gradually decreases;The maximum wear depth of the guide slipper when the shearer runs for 100 km is 4.379 mm.For guide slippers with a wear-resistant layer thickness of 6 mm,maintenance of the guide slipper is required after 450 h of operation.
