Abstract

At present, there is a surge in demand of accomplishing energy efficiency in the hydraulic power system, considering the conventional less efficient valve-controlled systems. For the rate and stroking cylinders, a design methodology has been developed based on the dynamic swivelling torque acting on the swash plate at maximum and minimum swash conditions. Furthermore, the dynamic behaviour of the pump is analysed to check if such torque balance concept can provide the acceptable performance or any modifications are required to meet the desired performance as a variable displacement pump. The optimum range of rate cylinder and stroking cylinder diameter has been evaluated according to the dynamic performance of the pump for the benefit of manufacturer. An experimental validation is also carried out at different loading conditions. The model has been used for performance prediction for wide variations in the load conditions. Next, using these dynamic performance predictions, the pressure-flow characteristics curves have been developed through simulation and found to be in excellent agreement with the manufacturer data.
