Abstract

The invention provides a double-pump separate-cavity adjusting control load simulation system. The double-pump separate-cavity adjusting control load simulation system comprises a simulator loading system and a steering engine system, and the simulator loading system comprises two hydraulic pumps, a loading actuator, a speed sensor and a force sensor. Two bidirectional metering pumps are separately connected with two cavities of the loading actuator, so that the flow or pressure of the two cavities of the loading actuator is adjusted, each bidirectional metering pump has two working modes including a flow control mode and a pressure control mode, a controller can generate a loading control instruction based on a load spectrum instruction and a force sensor feedback signal, the bidirectional metering pumps in the pressure control modes are adjusted, and the regulation and control on the pressure state of one cavity of the loading actuator are realized; and the controller can further generate a speed control instruction based on a speed reference instruction generated on line and a speed feedback signal of the loading actuator, and the flow state of the other cavity of the loading actuator is adjusted by adjusting the bidirectional metering pumps in the flow servo mode so as to decouple active motion interference of a steering engine.
