Finite Element Analysis of the Rolling Bearing Clearance Environmental Field with ANSYS

Abstract

Due to the complex structure of the rolling bearing, a simplified bearing model was founded and then thermal stress simulation was analyzed with ANSYS. The various parts of the displacement changes can be got. Compared the simulation results with the actual results, it can be drawn that the simulation result is basically same with the analytical result. So the simplified model is right. This method is simple, and can be adapted to the general clearance analysis.

The Finite Element Analysis of the Wind Turbines's Rotary Support

“…As the rotary support complex structure, more surface structure, some parts of the structure have little effect on the calculation results, but not conducive to the process of finite element analysis and calculation, so the actual situation can be simplified; to avoid calculation error caused by Stress distortion around concentrated force ,creating the prosthesis in the rotation round face and bottom in order to arrive the simple finite element model closer to the actual situation. Firstly,the rotation support is simplifyed in the Inventor [3] software ,then, the simplify geometric mode need to be imported into the finite element software ANSYS [4] , creating prosthesises and establishing the rotation support's finite element model. The finite element model is shown in Fig.…”
