【Abstract】 Aiming at the complex working conditions of a certain 4 t forklift truck, a potential energy recovery system for forklift trucks based on a motor-pump-composite accumulator is proposed. The principle of the system is analyzed, a mathematical model is established, and AMEsim software is used for simulation analysis., The results show that: the energy recovery module recovery rate based on the composite accumulator is 47.38%, which demonstrates the rationality of the system. In order to further improve the energy recovery rate, the parameters of the energy conversion element are optimized, and the optimized system recovery rate is increased by 4.39%, To provide a certain reference for further research on the potential energy recovery of hoisting machinery.更多还原
