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 pump, which cannot adjust the control strategy according to working conditions. It does not meet current trend energy-saving emission reduction. To this end, an electro-hydraulic machinery, permanent magnet synchronous motor quantitative is proposed. A variable LS differential pressure compensation valve improve machinery's performance are AMESim used establish simulation model obtain composite motion, control, performance. results show that achieves essential functions system. feasible. They can effectively adapt reduce energy consumption provide theoretical basis intellectualization electric machinery.
