Double-pump separate-cavity adjusting control load simulation system

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.

Description

technical field [0001] The invention discloses a dual-pump sub-chamber adjustment and control load simulation system, which belongs to the technical field of aviation simulation. Background technique [0002] When the aircraft is flying in the air, the attitude of the aircraft is adjusted mainly by adjusting the angle of the steering gear. The quality of the steering gear system directly determines the flight performance of the entire aircraft. The actual working environment of the steering gear is affected by a series of factors such as vibration, high temperature, and low temperature, which affects the reliability of the steering gear system and the robustness of the steering gear servo control algorithm. In order to reduce the cost of the research and development stage and the risk of the flight test, the on-load test has become a necessary experimental link in the development of the aircraft. [0003] The load simulation system is the key equipment for the on-load test...
