Pumped storage power station plays an important role in power grid in china. It reduces the cost of power grid and improves the reliability of power grid. Much attention has been paid to the characteristics of main parts of pumped storage power station. Strength, stiffness and fatigue properties of a conical tube of pumped storage power station are analyzed by finite element method, and economic and reasonable steel thickness are determined. Results show that the conical tube has good strength, stiffness and fatigue properties, and meets the allowable requirements.
