Embodiment Construction

[0059] The specific steps of a method for evaluating the reliability of command and communication equipment based on accelerated life tests are as follows:

[0060] The first step is to determine the environmental stress

[0061] According to the theory of storage life extension and accelerated life test, combined with the actual use environment of command and communication equipment, the environmental stress that affects the service life of the equipment is determined. The working environment of command and communication equipment is complex and diverse. It is necessary to determine the environmental stress that affects the service life according to the specific installation location and surrounding environment of the equipment. The 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 equipment includes: temperature, humi...

Abstract

The invention discloses a method for assessing the reliability of command and communication equipment based on an accelerated life test. The method includes the steps of environmental stress determination, electrical stress determination, environmental stress accelerated life model determination, electrical stress accelerated life model determination, accelerated life test profile determination. equipment detection, equipment failure analysis, maintenance cost analysis and service life assessment, and equipment weak-link analysis and reliability improvement. The method effectively judges weakparts restricting the use of the equipment, according to the occurrence time of failure, the failure time of the weak parts of the equipment is pre-estimated, and support is provided for formulation of a maintenance plan and a maintenance spare-part reserve scheme.

Description

technical field [0001] The invention relates to a method for evaluating the reliability of electronic equipment, in particular to a method for evaluating the reliability of command communication equipment based on accelerated life tests. Background technique [0002] Command and 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 economic efficiency of equipment use will be reduced. However, with the increase of equipment service time, its failure rate gradually increases, which reduces the reliability of equipment. If the components that restrict the service life of the equipment can be determined and the spare parts and maintenance can be reasonably arranged, the maintenance time of the equipment can be shortened, thereby improving the availability of the equipment; the actual service life of the equipment in service can be accurately evaluated, ...
