| Abstract: | Aiming at the energy waste of the boom hydraulic cylinder during the operation of agricultural loader, a hybrid energy recovery hydraulic system with energy storage elements and super capacitors is designed to improve energy utilization. Using AMESim to build a simulation model of the hydraulic system of an agricultural loader to study the energy recovery efficiency under different loads. The simulation results show that when the hydraulic cylinder drops, as the load increases, the greater the potential energy generated by the load, the smaller the energy required by the hydraulic pump. The energy recovery efficiency first increases and then decreases as the load increases. When the load is 5 t, the energy The recovery efficiency is the highest, up to 57.47%. The system can effectively realize the energy recovery function. |
