Electro-Hydraulic Load-Sensitive Simulation Study of Walking Hy-draulic System of Electric Agricultural Machinery
The conventional load-sensitive hydraulic drive chassis system for agricultural machinery uses a combination of engine and load-sensitive pump, which cannot adjust the control strategy according to the working conditions. It does not meet the current trend of energy-saving and emission reduction. To this end, an electro-hydraulic load-sensitive hydraulic drive chassis system for agricultural machinery, which uses a combination of permanent magnet synchronous motor and quantitative pump, is proposed. A variable LS differential pressure control and a variable differential pressure control of the pressure compensation valve to improve agricultural machinery's working performance are proposed. AMESim is used to establish the system simulation model to obtain the system composite motion, variable LS differential pressure control, and variable pressure differential control of the pressure compensation valve performance. The simulation results show that the system achieves the essential functions of a conventional load-sensitive system. The variable LS differential pressure control and the variable pressure differential control of the pressure compensation valve are feasible. They can effectively improve the performance of agricultural machinery to adapt to working conditions. It can effectively reduce the system energy consumption and provide a theoretical basis for the intellectualization of electric agricultural machinery.
