The study investigates and analyzes the possibilities of reducing the hydraulic resistance and increasing efficiency of the hydraulic actuator.
The proposed system is a four ports hydraulic cylinder fitted with a novel flow control valve. Goldenberg, "Design of a new high performance electrohydraulic actuator," in Proceedings of The International Conference on Advanced Intelligent Mechatronics, IEEE/ASME,, 1999, pp.
The proposed four ports cylinder was simulated and parameters such as ports sizes, loads and pressures are varied during the simulation.
The hydraulic resisting forces, piston speed and mass flow rates are computed. Chenoweth, Aircraft flight control actuation system design vol.
Results show that the hydraulic resistance is significantly reduced in the proposed four ports actuators; and the proposed cylinders run faster than the conventional cylinders and a considerable amount of energyis saved as well.
