Through studying the failure causes and distribution rules of aviation electronic airborne equipment under the comprehensive environmental stress conditions, we present a new reliability test methods combining the comprehensive test and accelerated reliability growth test. It is based on the reliability test theory of the physical fault ,considering the testing capability and facility test ,combining with the features of airborne equipment design ,using the assessment ideas of ultra-job stress test without changing the eqiupmengt failure machanism .In my paper , to realize diversity factors through reliability simulation model ,I study many kinds of specific technology , such as test method ,project management and application ,ultimately solve the engineering problem that environmental simulation test methods and traditional statistical reliability can not evaluate the airborne equipment under high reliability requirements within short development cycle .The new methods I put forward can make us reasonably set the integrated series of high stress values without changing the failure machanism of the product ,which can effective shorten the time of tese and save the costs.
