Abstract: |
Finite element analysis software ANSYS is used to analyze a bearing sleeve of satellite antenna in interference assembly condition, and then the factors affecting the inner diameter of the bearing sleeve shrink are studied. In the end, the method of optimizing the inner diameter tolerance of the bearing sleeve is presented, which can enhance the efficiency of mechanical design and assembly process dramatically. |
