本文利用有限单元法计算提升机卷筒各点的应力及变形。利用修改刚度矩阵及载荷列阵的方法较为精确地解决了在单层以及多层缠绕下的钢绳拉力降低的计算问题。文中对卷筒凸缘的载荷作了近似分析。提出了计算多层缠绕钢绳的提升机卷筒的程序(从略备查)。
In this paper, finite element method is used to calculate the stress and deformation of hoist drum. The method of modifying the stiffness matrix and the load array is more accurate to solve the calculation problem of the wire rope pull reduction under single-layer and multi-layer winding. In this paper, an approximate analysis of the load on the reel flange is made. A procedure for calculating the hoist drum of multi-layer wound steel wire rope is proposed.
