Investigation on the Cross Power Control of Axial Piston Double Pump Based on the Virtual Prototype

In order to improve the power control flexibility of axial piston double pump and reduce energy consumption, a cross power control mechanism of double pump is developed. Comparing with the traditional summation power control and individual power control methods, the cross power control can distribute the power into two different individual pumps according to the sum of operating pressure of the two pumps. A virtual prototype of displacement adjusting mechanism of the double pump was established to analyze the control flexibility and energy saving ability of the cross power control. With this prototype model, the power distributions were calculated and analyzed at different operating pressures. Besides, the sensing control system of negative load was also simulated by the model as an additional function. And both the experiment results and simulation results were used to prove the performance of summation power control. It is concluded form the simulation and experimental analysis that the cross-power control has advantages in control flexibility, power distribution and energy-saving ability.
