Разработка программы для расчета долговечности устройств обработки радиосигналов
The article examines the creation of program to assess the performance durability of radio-signals processing devices. This type devices are widely used in various communication systems and performance durability of these devices have a significant impact on performance durability communication systems. In the currently accepted methods of assessment of the durability indicators of device can be performing calculations in two stages (approximate and refined calculation). This is when a large number of elements significantly increases the complexity associated, primarily, with the search data on the durability characteristics. Therefore, given in the methods the model used for the conversion of durability indicators of the maximum allowed modes and conditions of the use of elements (approximate calculation) to operating modes (refined calculation), is quite simple. However, the use of such models although not strongly influences the complexity of the calculations, but may lead to less accurate estimates of durability indicators. This error will be greater than the maximum allowed modes and the conditions of application of elements differ from operating modes. However, modification of models aimed at improving the accuracy of the calculations that will lead not only to increased complexity of the calculations, but also requirements for the qualification of specialists and, consequently, to the need to create appropriate software and databases. In addition, the need to create such software due to the lack of commercial software tools for the calculation of reliability of domestic and foreign manufacturers of modules of calculation of durability. When creating the calculation program of durability indicators of the radio-signals processing devices were the main requirements, the scheme of information exchange with CAD-systems and specialized CAE-systems, to determine the composition of software modules and the functioning algorithm of the program and designed the model database according to the durability characteristics of elements. This research carried out in 2015 was supported by "The National Research University "Higher School of Economics" Academic Fund Program" grant (No. 15-05-0029).
