本文介绍了用有限元法计算水轮机主轴在扭矩作用下的位移及应力。计算时采用了自动剖分的四节点等参元、刚阵分块存鼓和块三对角追赶求解。并附有计算结果与试验结果的比较。
This paper introduces the finite element method to calculate the displacement and stress of turbine main shaft under torque. Calculated using the automatic subdivision of the four nodes isoparametric elements, just array block storage block and block three diagonal chase solution. And with the calculation results and the comparison of test results.
