The servo actuator system simulator has the advantages of complete system function, reasonable and compact structure, reliability in operation, convenience in use and good expansibility and tailorability.

Description

technical field [0001] The invention relates to a servo actuation system simulator and a simulation method thereof, in particular to an interface template controlled by a computer to realize servo actuation system interface signals and function simulation, and belongs to the technical field of engineering simulation. Background technique [0002] The flight control system is becoming more and more important in the design process of modern aircraft. With the application of fly-by-wire flight control technology and active control technology, the flight control system has reached the point where it is equally important and synchronized with the overall, aerodynamic, structure and strength of the aircraft. At the same time, the safety and reliability of the flight control system are more important to the safety of the aircraft. In order to ensure the safety and reliability of the flight control system, an important way is to carry out ground simulation tests on the basis of desig...

AI Technical Summary

Problems solved by technology

[0005] (1) The installed servo actuation system can only be produced and provided after the design of the flight control system is completed, which cannot meet the needs of the design and development stage test or the initial prototype stage test;

[0006] (2) The installed servo actuation system is developed and produced for a special flight control system and is not universal. After the status of other components of the flight control system changes, it needs to be adapted, or even reprocessed and produced;

[0007] (3) The cost of the installed servo actuation system is high and the cycle is long;

[0008] (4) The installed servo actuation system is completed by manual operation, the verification test process is inefficient and the cycle is long
