Comparative Experimental Study Of Rubber Transmission's Vibration Between Hydraulic And Electronic Drive

Integrated Full Electrical Propulsion,IFEP is a major research content and development direction for the ship industry,especially military ship.Based on the telescopic rudder transmission test bed,comparative study of rudder transmission's vibration between hydraulic drive and electronic drive is carried out,in order to discuss the feasibility of replacing the traditional hydraulic servo drive control with electronic servo drive control.The study details are as follows:Firstly,the overall design work of rudder drive test bed is completed,including test bed,proper passive rudder blade loading system,centralized control system and data collection system,according to the condition of different loading force and rotation speed.Secondly,the design of two drive system control methods are accomplished.Traditional hydraulic servo drive uses analog-digital hybrid method to control hydraulic cylinder smoothly and precisely with incremental PID.Electronic servo drive uses digital AC servo method,based on CANopen field communication to send target position control instructions through CAN network between the host computer and the motor server driver,and control electronic cylinder precisely.Lastly,vibration test of the two kinds of driving control modes under various working conditions is carried out,and the comparative analysis is investigated.The results indicate that the vibration intensity produced by rudder transmission is positively correlated with the rudder blade loading force and the angular velocity at the zero balance position;In the small loading force,low angular velocity conditions,vibration intensity produced by the two drive mode is similar,but in the larger loading force,higher angular velocity conditions,vibration intensity produced by electronic drive mode is obviously lower than hydraulic drive mode;In general,electronic drive control for rudder transmission exceeds traditional hydraulic drive control in system's vibration and stability,and the electrification scheme of ship steering system is feasible.
