Workbench Based Strength Analysis and Structural Optimization of Twin Spoke Turbine Disks in Aircraft Engines

Abstract

The strength analysis of double spoke turbine discs and traditional turbine discs was conducted using Workbench commercial finite element analysis software. The results showed that double spoke turbine discs have advantages in quality, but slightly inferior in strength to traditional turbine discs. Next, a parameterized direct optimization method was used to optimize the structure of double spoke turbine discs. The results showed that this optimization method improved the weight and strength of double spoke turbine discs.
