The article presents the results of the analysis of noise immunity of analog EM nodes for the example of amplifying devices in integrated design, presents the results of noise immunity analysis, presents its estimates and recommendations on noise-proof design of amplifying nodes, substantiates the expediency of using two fundamentally different characteristics of noise immunity - the effectiveness of protection and noise immunity
The article considers the questions assessing the reliability of mechanical components used in the electronic equipment in the early stages of design. The calculations of failure rates springs shock absorbers according to various methods. It is shown that the use of models failure rates of mechanical elements, taking into account the peculiarities of their structural and technological performance, not only allows us to solve the problem of calculating, but also to ensure the required level of reliability and mechanical components, and containing electronic equipment.
Enterprises of Russia’s radio industry engaged in development and production of electronic instrumentation (EI) for space vehicles (SV), face problems of insuring reliability, and, first of all, problems of failure-free operation. Failures during EI acceptance tests and accidents at SV operation are real evidence of mentioned problems. One of the reasons of such situation is application of out-of-date and inaccurate methods of estimating the reliability of SV EI at the design stage where developers embed the reliability that will be realized during production and supported at the operation stage.
On the other hand, use of the "lower" estimates of failure-free operation parameters can lead to decrease of SV EI competitiveness, as this way in order to enhance reliability, manufactures unreasonably use various additional ways that lead to deterioration of economic, mass-dimensional and other indices. Therefore, increase of accuracy of estimating the reliability of SV EI with long terms of active existence is pressing problem, in particular for EI wherein redundancy as well as reconfiguration is used to ensure reliability.
In this paper the comparative characteristics of the РС ASONIKA-K and PМ of reliability calculations are given.
