[Abstract]:Electro-hydraulic load simulator is a typical mechanical-electro-hydraulic integrated system. Under laboratory conditions, it can simulate the air torque affected by the flight altitude, surrounding air flow, rudder surface position and other factors on the rudder surface of the aircraft. It is an important part of hardware-in-the-loop simulation system. In this paper, a set of electro-hydraulic load simulator test system is designed, the concrete work is as follows: (1) Mechanical structure design of electro-hydraulic load simulator test system: in this paper, two electro-hydraulic servo motors are designed as executive elements to simulate the motion of steering gear and the force of air on rudder shaft respectively. The steering gear motor can change the distance between the steering gear motor and the loading motor along the slide path to simulate the steering gear with different structural parameters. Its structure design takes safety first, standardization, module as the design principle, fully considers the installation interface of each module of the mechanical body, the installation connection with each module of the hydraulic system and the electrical wiring inside the structure. (2) hydraulic system design of electro-hydraulic load simulator test system: as the dynamic element of the executive element of the whole system, the hydraulic system designed in this paper has the characteristics of high precision, high response and high power utilization ratio. In the structure, the side type is used to reduce the height and the mechanical body is integrated; at the same time, the vibration isolation measures are introduced in all kinds of possible vibration places; the centralized control is realized, and all the controllable quantities of the hydraulic station are introduced to the pump control unit of the control cabinet for centralized monitoring and control. (3) the hardware design of the control system of the electro-hydraulic load simulator test system: taking the industrial control computer, A / D, D / A modules as the core, the four units of control, distribution, pump control and digital processing different types and different functional signals are integrated. The four units are assigned uniformly by the industrial control computer. (4) Research on control algorithm, simulation and experiment of electro-hydraulic load simulator: in this paper, a control algorithm of force feedforward compensation is proposed through theoretical derivation and simulation, and the parameter model controller of load simulator is designed by using this method. Finally, the effectiveness of the force feedforward compensation method is verified by experiments.
