| Summary: | To predict the press-mounting quality, Aiming at the armature component’s press-fit process, the simulation was implemented on the press-fit process by using ANSYS Workbench. Thus the interference value’s rational scope and press-fit cure’s rational scope were obtained. On this base, the simulation was implemented on armature’s tilt press-mounting work. The results show that press-fit surface and bore of part’s tilt angle are main influence factors for press-mounting parallelism. When the press-mounting surface or the bore of part’s tilt angle was more than 0.03°, parts will be damaged, so the tilt angle should be less than 0.03°. On the basis of the simulation research mentioned above, the precise press-mounting experiment device was developed and fabricated for the press-mounting work of armature component, in which it included force sensor, the grating ruler and machine vision. The press-mounting experiments were carried out on the device. The results show that the difference between press-fit curves obtained from FEA and these obtained from experiment is relatively small. The deviation between maximum press-mounting force obtained from FEA and maximum push-out force obtained from experiment is 2.3%. In addition, the maximum push-out force obtained from experiment is 15% lower than maximum press-mounting force obtained from experiment. According to the comparison results, the press-mounting experiment results are correct, and then the FEA results can be applied for predicting the precise press-mounting quality. |
