[Objectives] A comparative study of the rudder transmission vibration characteristics of electric drive and traditional hydraulic drive is carried out on the basis of a telescopic rudder transmission test bed.[Method] First,a study is made of the rotational angular velocity and the relationship between the vibration characteristics and load force of a rudder transmission driven by an electric servo motor. Next, the vibration characteristics of the mechanism under hydraulic drive and electric drive are compared and analyzed.[Results] The results indicate that the vibration intensity has a positive correlation with the rudder blade loading force and angular velocity at the zero balance position. Both the peak-to-peak values and root-mean-square values of the vibration acceleration of the electric drive are reduced by 40% compared with the hydraulic drive, meaning that the electric drive can more effectively reduce the overall vibration of the rudder transmission.[Conclusions] The results provide a reference for the electrification of the rudder transmission.
