Finite Element Analysis for Steel Bifurcation Pipe of Zhanghewan Pumped Storage Power Station

Abstract

Pressure pipeline's length to diameter ratio is very big, easy to instability, stress situation more complex than the pressure vesse. The numerical simulation study for pressure pipeline on water security is of great significance. Static analysis of pressure pipeline is the foundation of design and construction of pressure pipeline, through static analysis, can get the change law of stress and displacement of the pressure pipeline. The stress and strain of pressure pipeline structure are the index of pressure pipeline structure rigidity. Penstock is an important part of building in the water conservancy and hydropower project. In this paper, finite element analysis software is used to do structural computer simulation analysis for steel bifurcation pipe of Zhanghewan Pumped Storage Power Station, and we have summarized the variation of stress and displacement. We studied the stress and displacement bifurcation structure of complex parts, and had got the results and some useful conclusions.
