Optimization of Geometric Parameters for Turbine Blades Based on Inverse Adjustments

Abstract:

In order to conform to the dimensional tolerances of wax pattern die-profile for turbine blade in investment casting process, an optimization method of geometric parameter for turbine blades based on inverse adjustment was proposed. The geometric parameters for optimizing were extracted, and the bending and torsional deformation can be compensation. Therefore the nonlinear deformation compensation during solidification and cooling procedure can be efficiently realized. This method finally exhibits its advantage over the traditional linear scaling method. It set the theoretical foundation on optimization method of die-cavity for turbine blade. The die-profile optimization system which was developed in this paper proves better effect for the die-cavity design.
