Method for generating multistage task system fault physical simulation sections of avionic devices

Abstract

The invention provides a method for generating multistage task system fault physical simulation sections of avionic devices. The method comprises the following steps: 1, determining a plurality of task stages of an airplane of an avionic device in a flight mission period and the duration time of each task stage; 2, determining the environment temperature of the avionic device in the task stages so as to generate an environment temperature section; 3, determining the vibration of the avionic device in the task stages so as to generate a vibration section; 4, determining the humidity of the avionic device in the task stages so as to generate a humidity section; and 5, enabling the time points of the task stages of the temperature section, the vibration section and the humidity section to correspond to each other, so as to generate a fault physical comprehensive simulation section of the avionic device. According to the method, the weak links of the avionic devices can be determined in allusion to reliable simulation results, so as to provide basis for the design improvement of products.

Description

technical field [0001] The invention provides a method for generating a reliability simulation profile of avionics equipment, in particular to a method for generating a reliability simulation profile under a multi-stage task system considering the life cycle of avionics equipment, and belongs to the field of reliability simulation of electronic equipment. Background technique [0002] Failure physics believes that the failure of electronic products is directly related to the external environment and load it bears. Different environments, load values, and even different environmental load change sequences may cause different types of failure mechanisms and failure times. The existing reliability simulation profile generation method refers to the electronic equipment reliability qualification test profile generation method to obtain the environmental profile under typical tasks, and avionics often perform multiple different tasks in its life cycle, such as: aircraft Flight can...
