摘　　要：建立了以截齿崩落线方程和交点坐标方程为代表的切屑图的数学模型,基于MATLAB/GUI设计了横轴式掘进机截割头切屑图的人机界面系统。利用该系统,通过在界面上输入截割头的相应参数,就能模拟掘进机截割不同煤岩时、不同工况参数下的横轴式掘进机的切削过程和切屑图。通过以国产某型掘进机为例进行模拟,获得了该掘进机在不同参数下的切屑图,根据切屑图比较分析了截齿的受力状态、切屑厚度与截割粉尘量以及截割阻力的大小,为提高截割头设计水平、研究横轴式掘进机的截割过程,改善该型掘进机的截割性能奠定了基础。Mathematical model of grooving section pattern taking caving line equation of the pick and intersecting point equation as representative was set up, man-machine contact surface system of grooving section patterns for the horizontal cutting header based on MATLAB/GUI was designed. Through inputting corresponding parameters of the cutting head on the contact surface, the cutting process and grooving section patterns of the horizontal cutting header cutting different coal and rock under different operating mode parameters were all simulated. Taking the certain type horizontal-axial-roadheader for example to simulate, the grooving section pattern under different parameters was obtained, and compared with force conditions of the cutting picks, chip thickness, cutting dust capacity and size of the cutting resistance were also analyzed, which laid foundation for improving design level of the cutting head, researching the cutting process of the horizontal-axial-roadheader and improving cutting performance of the machine.
