Abstract
This paper describes the development and application prospects of the ANSYS, and shows the powerful function and the practical value of the ANSYS by the finite element analysis of the steam turbo-generator rotor. With the emergence of the finite element method and the development of computer technology computer technology, we put forward higher requirements for product. So this article uses the sub-model technology of the ANSYS for analyze the digging phenomenon of the steam turbo-generator rotor. Sub-model technology is a finite element technique that used in some regions to solve a more accurate solution. The advantages are solving an exact solution of a part of the model and reducing the transfer region of the finite element model and analyzing the different designs in specific regions and helping to prove the adequacy of fine mesh.
This study uses the Parametric Design Language (APDL) of the ANSYS for rough model and sub-model, and through the direction of displacement and stress and other data to analysis the reliability of the steam turbo-generator rotor. Putting the pressure average assigned to the surface, and I got the maximum displacement and the maximum stress values by solving the components in the working conditions. Hope that through the computer-aided design and the finite element analysis for the design skills upgrading of the steam turbo-generator rotor.
