摘要
本文讨论采煤机螺旋滚筒的强度问题,用三角板单元编制了有限元程序SHEAR1,为了减少计算机内存和便于计算,采用了一维变带宽存储和网格自动生成。实测数据与计算结果基本一致。
This paper discuissed the strength problem of helical shearer drum.
The program SHEARl of the finite element is workd out with triangl plate unit
In order to reduce internal memory of computer and make computing easy,
the methods of one dimensional changing bandwidth memory and automatical netwoork generation are used. Actual measurements are basically in accordance with the calculation results.
