Research on vibration and noise reduction of reducer based on tooth modification
Aiming at the vibration and noise problems caused by the internal excitation of the transmis-sion system in a specific electric drive system,a dynamic model was established by Romax Designer software.In order to reduce the transmission error,genetic algorithm was used to solve the gear modification optimal val-ue of the double gear reducer,and the modification parameters are put into the model for contact analysis.Compared with multiple simulation results before and after optimization,it is found that the transmission error value,maximum contact stress,load distribution and peak value per unit length,Fung stress of gear tooth root,modal flexibility,energy,surface acceleration and sound pressure value before and after modification are reduced to varying degrees,which effectively reduces the vibration and noise caused by internal excitation of the transmission system,and improves the life of the system and the stability of transmission.
