Abstract

Abstract: By the finite element method of multi-body contact problem, the time-variable stiffness at different rotational position of a new type gear reducer with small tooth number difference was obtained, and the dynamic contact finite element method was used to analyze the meshing impact, and then the internal excitation which composed of the excitations of time-variable stiffness, gear error and meshing impact were calculated. A dynamic finite element model of reducer was established and used to analyze the dynamic response of time-domain and frequency-domain as well as one-third octave acceleration grade structural borne noise of gear reducer under dynamic excitation. At last an experiment of vibration analysis of reducer was conducted using the analysis instrument of vibration test. The computational results obtained are in a good agreement with the data of experimental tests.
