| Abstract: | The paper introduced the basic principle of modal analysis, and taking plane cam in free state as an example, analyzed and obtained the distribution maps of its first nine step modality natural vibration frequency, the modality of vibration mode, the relative displacement and the relative stress using the ANSYS software. This analysis result showed the structure vibration intensity distribution of the various parts of the cam, and provided the essential basis for the cam mechanism dynamics optimization desi... |
