To deduce the necessary results, the hydraulic flow rate and its corresponding pressure were taken to be proportional to the speed and acceleration of the hydraulic piston. Using analytical software, a hydraulic circuit was designed to sense the load and control the behavior of high-pressure hydraulic cylinder and other constituents. For this purpose, the system was modeled using computational dynamics, where ninth-order differential equations were derived and simulated to extract the required results on the system components. The time responses of the state variables were also obtained. The credibility of which was determined by analyzing and interpreting the simulation results against those calculated during the design process. Results showed that by solving these equations, the time responses of the state variables were obtained. By analyzing and interpreting them, the performance of the hydraulic circuit was validated. Although, the use of the load sensor in order to follow the pump pressure from the load pressure changes was confirmed. load sensing axial piston pump swash plate suction rod pump special hydraulic cylinder Full Text Additional Declarations No competing interests reported.
