| 针对辊压机在工程应用中出现的辊面脱落或柱钉断裂等现象,本文对轴压机辊面进行了受力分析及有限元分析,获得了辊面应力分布云图和变形分布云图,结合工程工艺需求,对棱柱型柱钉排列方式进行了对比分析。结果表明：棱长为12mm的柱钉、轴线方向为25/27、环向数量为200时,在深度为40mm和50mm柱钉交错排列,凸出辊面高度值为3mm时比棱长为14mm时辊面的最大应力和最大变形都有所减少,其方案最优。 |

| In order to solve the problems of roller surface peeling off or column pin breaking off that often occur in the engineering application of roller press, this paper conducts force analysis and finite element analysis on the roller surface of the roller press, obtains the stress distribution cloud map and deformation distribution cloud map of the roller surface, and conducts a comparative analysis of the arrangement method of the cuboidal column pin with reference to the engineering process requirements. The results show that when the edge length of the column pin is 12mm, the axial direction is 25/27, the circumferential number is 200, the depth is 40mm and 50mm, the column pins are staggered and protrude 3mm from the roller surface, the maximum stress and maximum deformation of the roller surface are reduced compared with the case of the edge length of 14mm, and the scheme is optimal. |
