Hydraulic Fluid Variables

Part of a hydraulic tool box to generalize the hydraulic system simulation. The outcome of the block are a global hydraulic fluid variables based on the current system pressure and temperature.

Here is a simple Simulink file to calculate the stiffness of hydraulic spring.The theory is explained in my book:M Galal Rabie, Fluid power Engineering, McGraw-Hill, NY, 2009, pp 235-237

Lumped Parameter Model of Hydraulic Transmission lineHere is a lumped parameter model of a hydraulic transmission line.The line is modeled by one, two, three, four and ten lump models.The simulation program presents the transient response in addition to experimental results.The theory is...

Hydraulic servo actuators (HSAs) are used to precisely control displacement in a wide range of equipment. Generally, a hydraulic servo actuator consists of a hydraulic actuator controlled by a directional control valve of an infinite number of positions and equipped with a feedback arrangement....
