通过五个力学模型的有限元分析计算,找出了蜗壳座环打压状态下经济而准确的应力计算方法,其计算结果与电站实测值很接近。此项工作为今后研究蜗壳座环与混凝土联合受力问题打下了基础。
The finite element analysis of five mechanical models is used to find out the economical and accurate stress calculation method when the volute ring seat is pressed. The calculated result is close to the measured value of power plant. This work laid the foundation for future study on the combined stress of volute seat ring and concrete.
