Aircraft equipment durability design method and aircraft equipment durability design system

Abstract

The invention discloses an aircraft equipment durability design method and an aircraft equipment durability design system. The aircraft equipment durability design method comprises the following steps: 1) determining the durability index requirement of equipment to be designed; 2) determining the wear-out failure mechanisms of the equipment to be designed in a whole life cycle, and the synthetic stress of each wear-out failure mechanism; 3) judging the type of the wear-out failure mechanism of each component in the equipment to be designed; 4) independently calculating the theoretic service life of each component; and 5) judging whether the theoretic service life of each component meets the durability index requirement in the 1). The invention provides the aircraft equipment durability design method, which fills up the technical blank in engineering development and provides a powerful basis for subsequent models to develop the durability design analysis work of airborne equipment.

Description

technical field [0001] The invention relates to the technical field of aviation product testing, in particular to an aircraft equipment durability design method and an aircraft equipment durability design system. Background technique [0002] With the rapid development of my country's aviation industry, the life index requirements of aircraft airborne equipment are getting higher and higher, and the greatly increased life requirements have greatly increased the complexity of wear-out failure mechanisms within the life of equipment and increased the durability of products. Weak links bring huge development difficulties to the realization of the long-life requirements of the airborne equipment of the model. In the previous model development, no durability design analysis work was carried out, and there was a lack of corresponding durability design analysis process and application technology. [0003] Therefore, it is desirable to have a technical solution to overcome or at lea...
