摘要
通过对EML340型连续采煤机的截割部受力状态及边界条件的合理简化,得出了截割部有限元计算结果及模态分析结果,该计算方法在工业性试验中得到了很好的验证。为连续采煤机截割部的计算提供了一种可行的方法。
By predigesting logically the force and boundary conditions of cutting unit in the type of EML340 continuous miner, the results of a finite element model and modal analysis can be obtained. This ealculational method can he useful for the calculation of cutting unit,which has been well validated in the industrial experimentations.
