摘要

基于采煤机截齿力学模型,运用Matlab开发了交叉式及顺序式排列的滚筒载荷计算程序,获得了5种典型工况下滚筒的载荷谱、截割性能参数及块煤率;通过三维离散元软件PFC分析了两种截齿排列方式的采煤机装煤性能;基于Pro/E、Matlab、Ansys、Adams联合仿真,分析了不同工况下采煤机关键零件的可靠性。研究结果表明:当采煤机截割三层夹矸煤时,截齿应采用顺序式排列,其载荷波动小,工作可靠性高;一般工况下,截齿采用交叉式排列可提高采煤机的块煤率,与顺序式相比,切削面积提高1.99倍,方正率提高21%。

Abstract

The drum ’s load calculation program of the staggered and sequential arrangement has been developed by MATLAB based on the shearer cutting mechanics model,which can get drum load spectrum,cutting performance parameters and the rate of lump coal under 5 typical working conditions;Shearer loading performance of two picks arrangement were analyzed by three-dimensional discrete element software PFC;The reliability of the key parts of the coal machine under different conditions has been analyzed Based on the PRO/E,MATLAB,ANSYS and ADAMS.The results show that:When the coal is cutting coal gangue,the pick should be used in sequential order,the load fluctuation is small and the reliability is high;Under normal conditions,the sequential pick arrangement of shearer can improve the lump coal rate,the cutting area will increased 1.99 times and the founder rate will increased 21% compared with the sequential type.
