我国生产的2.5M矿山提升机主轴因有缺陷或裂纹而报废的损失是相当严重的。因此,这种大型主轴的断裂力学研究对制定其探伤标准有十分重要的意义。本文探讨了2.5M矿山提升机主轴的有限元分析。我们应用了从美国引进的结构分析和程序SAP5(A STRNCTRAL ANA LYSIS PROGRAM)于1980年11月在北京汽车厂的EC1040计算机上进行计算,采用三维8～21可变节点等(次)参单元,模型的单元数为372,节点总数为836,方程总数为2502,总CPU时间为25分钟。分析表明,计算结果是比较理想的,这就为进一步对主轴进行断裂力学分析提供了比较精确,可靠的依据条件。
2.5M mine hoist spindle production due to defects or cracks scrapped the loss is quite serious. Therefore, the study of fracture mechanics of such a large spindle is very important for the development of its testing standards. This article discusses the 2.5M mine hoist spindle finite element analysis. We use the structural analysis and program SAP5 (A STRNCTRAL ANA LYSIS PROGRAM) introduced from the United States in November 1980 at the Beijing Automotive Plant EC1040 computer to calculate the use of three-dimensional 8 ~ 21 variable nodes such as () The number of units in the model is 372, the total number of nodes is 836, the total number of equations is 2502, and the total CPU time is 25 minutes. The analysis shows that the calculation result is ideal, which provides a more accurate and reliable basis for the fracture mechanics analysis of the main shaft.
