| General | A shaft is inserted tightly into a slightly smaller hole in another part. The shaft is metal and the part with a hole is resin. Mating/un-mating analysis is conducted as well. |
|---|---|
| Analysis Model | For the purpose of stable analysis and faster calculation, a symmetric model is used. A contactor boundary condition is set to the resin body and a contactee boundary condition is set to the metal shaft. The two planes of symmetry are applied symmetric boundary condition. |
| Result | The results with and without friction are compared. With friction, the press-fit force increases in proportion to the insertion distance. Without friction, the press-fit force is stable regardless of the insertion distance. |
