针对掘进机工作时截齿磨损严重,造成大量经济损失的实际,为了探究影响截齿磨损的因素,利用ABAQUS软件的显式动力分析模块对掘进机用镐形截齿的截煤过程进行了数值模拟,得到了不同合金头锥角镐形截齿在截割煤体过程中的应力分布云图以及截割全过程的应力曲线。
In order to find out the factors that affect the wear of picks, the explicit dynamic analysis module of ABAQUS software was used to carry out the numerical simulation of the pick-up process of picks with picks The stress distribution curves and the stress curves in the whole process of cutting the coal were obtained by simulating the different angles of picks of the alloy.
