THE INFLUENCE OF EXTERNAL DISTURBING FACTORS ON THE DURABILITY OF MICROWAVE DEVICES

621.3.029

This article is about consideration must be given to durability’s indexes of SHF devices including mechanical parts. Only electronic parts of SHF devices are considered at evaluating reliability of whole device and mechanical parts are supposed reliable very much, almost failure-free. But mechanical parts may be exposed to effects of deterioration and destruction processesе, they are able to deform and change their material properties – flexibility, electroconductivity, magnet properties and etc. It shows interconnection of electronic and mechanical parts of SHF devices. Necessary to mention, that this interconnection is very difficult to describe. That’s why it so important to be able to properly evaluate reliability both mechanical and electronic parts and their durability. Ways of solving these problems are initiated in this article and described analysis of methods for evaluating reliability of mechanical parts.
