Abstract:Aimed at a planetary transmission with small tooth number difference, improved structural design was executed firstly. Secondly, by means of the dynamic contact finite element method, the internal dynamic excitations of teeth mesh were obtained, including mesh stiffness excitation, transmission error excitation and mesh impact excitation. Thirdly, according to the established model for dynamic finite element modal analysis, the natural frequencies and mode shapes of the planetary transmission were calculated, and its structural dynamic response and structural noise were researched with the comprehensive consideration of internal and external excitations. Finally, the noise and vibration testing was carried out utilizing the vibration test equipment. The results confirm that the predicted values are consistent with the experimental results.
