采煤机行走部导向滑靴中部撕裂问题分析与改进

Analysis and Improvement of the Tearing Problem in the Middle of the Guiding Sliding Boot of the Coal Miner Walking Section

针对某煤炭企业采煤机行走部导向滑靴中部撕裂问题,借助ANSYS仿真计算软件,开展了撕裂问题仿真分析工作,得出右铰耳与中部板连接处和铰耳的下圆角处应力较为集中是导致导向滑靴中部撕裂的主要原因。通过将两个铰耳与中部板两节位置的过渡圆角半径和铰耳孔位置的圆角半径增大的方法完成了改进,结果表明,改进后导向滑靴的最大应力数值相较于改进之前降低了42.6 MPa,取得了很好的改进效果,保证了导向滑靴工作的可靠性。

With the help of ANSYS simulation software,a simulation analysis of the tearing problem was carried out for the middle of the guiding slide shoe of the walking part of a coal mining machine in a coal mining enterprise.The results showed that the maximum stress value of the improved guide shoe was reduced by 42.6 MPa compared with that before the improvement,which achieved a good improvement effect and ensured the reliability of the guide shoe.
