Hydraulic circuits have been employed by automotive, aerospace, oil & gas and mining industries for an extended amount of time. During the design stage of the hydraulic circuits, the system level dynamic interactions between components need to be analyzed to enhance system performance and reliability. Physics based, low dimensional modeling and simulation is proposed to help system level design and to verify proper operation of hydraulic components. Presented in this paper is physics based modeling process of a hydraulic circuit. Low dimensional model of the hydraulic circuit is used to investigate dynamic interactions between components on MATLAB-Simscape® platform. The existence of hydraulic oscillations due to aging regulator seals is simulated and a method to reduce these oscillations is presented. It is also shown that the inadequate source to supply pilot pressure to hydraulically piloted valves can create similar hydraulic oscillations and reduce system reliability and remaining operational life.
