Abstract

Abstract: In this paper, the stresses of wheel-shaft shrinkage fit problem of the steam turbine are analytized using elastic contact finite element method and compared with Second Calculating Method. And then two schemes to reasonably design the wheel-shaft shrinkage re proposed. It is shown that elastic contact finite element method is important to stress analysis and innovating design of steam turbine.

Key words: 过盈配合, 叶轮, 有限元法, aerodynamic performance, double multiple stream tubes mode, pitch strategy, H-type VAWT
