Simulation research on high speed centrifugal residual stress homogenization of turbine disk

Abstract

 At present, problems such as excessive residual stress, local stress concentration and machining deformation are common encountered in the production and processing of turbine disk. In order to further improve the machining quality and performance of turbine disk components, a high speed centrifugal stress homogenization and strengthening method with in-depth research and application value is proposed in this paper. The simulation research on the centrifugal stress homogenization effect of turbine disk forging blank is carried out, and the distribution of residual stress at different speeds is obtained, the influence of rotating speed on stress homogenization effect is summarized.
