[0002] In the development process of the new generation of aerospace equipment, its development trend of high reliability, high precision and strong performance has put forward higher requirements for the development process of aerospace products. At present, there are many hidden dangers in the scientific research and production of aerospace electromechanical products. Some products appear in the Situations where it does not work properly in a complex environment

After analysis, the reasons for this problem are, on the one hand, the structure of aerospace electromechanical products is complex, involving multiple disciplines such as mechanical systems, control systems, and circuit systems. The contradiction between the characteristics and the high-density task requirements of the model is becoming increasingly prominent. On the other hand, the limitations of the existin
