Conventional hydraulic cylinders are simulated in FLUENT. Singh, "Derivation of design requirements for optimization of a high performance hydrostatic actuation system," International Journal of Fluid Power, vol.
Results show that the small outlet ports are the sources of energy loss in hydraulic cylinders.
A new hydraulic system was proposed as a solution to relieve the hydraulic resistance in the actuators.
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.
