ANALYSIS OF METHODS FOR CALCULATING THE RELIABILITY OF RAILWAY AUTOMATION SYSTEMS WITH ELECTRONIC COMPONENTS

Testing of electronic products railway automation involves assessing the indicators their functional safety and reliability. Reliability standards are very high. Confirmation these is mostly performed by calculation method [8]. For this purpose, branching technique applied. The initial data for calculations reference failure rates elements product under study. In industry methodology, it recommended to obtain from time directory, or other available sources. Directories late twentieth century not relevant today. Among current books MIL-HDBK-217 F. Military handbook. prediction equipment. 1991, published in United States. This guide used vast majority domestic developers products. However, there certain methodological problems that hinder use methods above document. particular, provide values rates, which characterize maximum load on element. actual calculated will be significantly lower than maximum. given American reflect minimum possible values. case, higher reference. It obvious joint methodology correct. addition, operates with more parameters. A way out situation proposed. If researcher uses value, he obliged as much additional possible. Not all such can correctly researchers. Therefore, a comparative analysis formulas two Identical parameters differences indicated. Conclusions made adaptation ratio source requirements.
