[Abstract]:The steering gear electric loader is used to simulate the force on the wing of the aircraft in the laboratory. It is a kind of hardware-in-the-loop simulation system working on the ground. It uses the motor to simulate the air resistance to apply the load to the steering gear. With the rapid development of national defense in China, higher requirements have been put forward for the actuation accuracy and response dynamic performance of the aircraft steering gear, as well as for the dynamic performance of the electric loading system, such as precision and fast response. This paper first introduces the background of the subject, summarizes the research status in the field of steering gear loading, as well as the development of related technologies. This paper introduces the overall scheme design of the system and the selection and working principle of important components. Then the loading motor, steering gear and other components are analyzed theoretically, and the mathematical model is constructed. This paper introduces the hardware circuit design of each component in detail. Starting from the core control chip and gradually expanding to the peripheral circuit, this paper introduces the structure of the components which play an important role in the peripheral circuit, and gives the analysis and explanation. It mainly includes the core controller circuit, power module, signal conditioning circuit, bridge acquisition circuit, position and speed detection circuit, current and voltage detection circuit and so on. This paper introduces the composition and design principle of the system software system, and gives the program design of the main function module combined with the system. Finally, the simulation results show that the loading system has fast response and precision, which shows to a certain extent that the design method of the system is effective and feasible.
