Study on Structural Reliability Analysis of Aircraft Electronic Equipment

Abstract

The aircraft electronic devices are mainly composed of plate type, the structures with so many electronic components are complex. Most electronic components are standard parts. Reliability analysis of aircraft electronic equipment is mainly focused on the circuit of electronic equipment and components and so on. However, the investigation about reliability of electronic equipment structure research is seldom. This article introduces the principle and method of structural reliability of aircraft electronic equipment. Taking the computer box of air data processing for a type of aircraft as an example, reliability analysis process is described based on Monte Carlo Method. the result of calculating the strength and stiffness reliability of the box are 99.9746% and 99.9833% respectively, while the experimental reliability are 99.9986% and 99.9918%. The good consistency between simulation and experiment results indicates that the analysis method is reasonable and effective.
