OS-E: 0400 Compressor Wheel
OptiStruct was used to run a free-free normal modes analysis on a gas turbine compressor wheel solid FE model.
Model Description
A solid hexa model of a gas turbine compressor wheel with fins was generated with HyperMesh. The model contained 44,369 grids and 31,022 solid hexa elements. A free-free modal analysis was conducted using OptiStruct to find the first twelve natural frequencies.
Results
The first six frequencies found were rigid body modes and can be disregarded.
