Radial Deformation Analysis of Complex Parts with Centrifugal Force and Heat Effect

Abstract:

A stream turbine bowed and twisted blade has been taken as an example for complex parts. Firstly, a simplified computing method for the blade with centrifugal effect is put forward. Then the finite element model of complex parts with centrifugal effect is established. Simulation results show that errors between calculation and simulation results are less than 15%, the simplified computing method has good application value. In addition, the impacts of centrifugal and heat on blade radial deformation are discussed by thermal structural coupling analysis. Numerical simulation results show that heat is the major factor that affects blade radial deformation.
