Abstract
Potential energy regeneration system, which shares an electrical energy storage device with power system, can further improve the fuel economy of hybrid construction machinery without much additional expense. However, the conventional potential energy regeneration system also results in poorer dynamic performance of actuators in comparison to throttle-governing system. In addition, the capacity of the regenerator should be large enough to avoid overload. Based on comprehensive consideration, this article presents a compound potential energy regeneration system that combines the regeneration device and throttle together. The regenerative torque is adaptive to load so as to keep the pressure drop over the throttle almost constant, and then the actuator can be governed by adjusting the opening of the throttle. The compound potential energy regeneration system is analyzed and evaluated using the frequency domain method and nonlinear simulation. Finally, experiments under different parameter conditions are carried out, and some useful design reference is provided. The simulation and experimental results show the effectiveness of the designed system as well as its control strategy.
