Development of experimental design for hydraulic active heave compensation systems

Abstract

The article presented here describes the development of test stand for hydraulic active heave compensation system. For measurements, actual position of hydraulic cylinder was used displacement sensors by the authors. They measured actual position of hydraulic motor by means incremental encoder. The test stand was built with the use of force sensor and 3 DOF accelerometer and gyroscope. During experimental tests force, acceleration and rotations (Pitch and Roll) were measured. Authors used two servo valves for the controlled position of hydraulic cylinder and hydraulic motor. The control system was based on PLC controller type Power Panel 500. The performed test included step response of hydraulic motor and hydraulic cylinder for sine signal.
