Embodiment Construction

[0059] The specific steps of a reliability assessment method for command communication equipment based on accelerated life test are:

[0060] Step 1 Determining Environmental Stresses

[0061] According to the storage life extension theory and the accelerated life test theory, combined with the actual use environment of the command communication equipment, the environmental stress affecting the service life of the equipment is determined. The working environment of command communication equipment is complex and diverse, and it is necessary to determine the environmental stress that affects the service life according to the specific installation location of the equipment and the surrounding environment. The determination of this stress is determined with reference to the failure and failure analysis conclusions of similar equipment. In relatively clean spaces such as shelters, the environmental stress that affects the service life of the equipment includes: temperature, humidi...

Abstract

The invention discloses a method for evaluating the reliability of command and communication equipment based on an accelerated life test. By determining the environmental stress, determining the electrical stress, determining the accelerated life model of the environmental stress, determining the accelerated life model of the electrical stress, determining the profile of the accelerated life test, and detecting the equipment, The steps of equipment failure analysis, maintenance cost analysis and life evaluation, equipment weak link analysis and reliability improvement are realized. The invention effectively determines the weak parts that restrict the use of equipment, estimates the failure time of the weak parts of the equipment according to the timing of the failure, and provides support for the formulation of maintenance plans and maintenance spare parts reserve schemes.

Description

technical field [0001] The invention relates to a reliability evaluation method of electronic equipment, in particular to a reliability evaluation method of command communication equipment based on accelerated life test. Background technique [0002] Command communication equipment has a specific design life. If the design life is reached and new equipment is replaced, the residual value of the original equipment will be wasted and the economy of equipment use will be reduced. However, with the increase of the service time of the equipment, its failure rate gradually increases, which reduces the reliability of the equipment. If the components that restrict the service life of the equipment can be identified and the spare parts and maintenance can be arranged reasonably, the equipment maintenance time can be shortened, thereby improving the availability of the equipment; the actual service life of the in-service equipment can be accurately evaluated, and batch replacements ar...
