Abstract

This article is about reaching and securing high reliability and safety in engineering systems during the design and testing of developmental prototypes. A new approach to and technique of calculation of the design reliability is proposed, taking into account both kinds of failure rates, those that are constant and those that change over time. The function for calculation of design reliability is represented by the product of three constituents of failsafe operation probabilities throughout the whole period of operation, considering the calculation of the reliability of mechanical components and metalwork. The calculation model proposed for reaching and securing the required reliability and safety levels takes into account controlling actions. A new approach and technique, as well as mathematical models, for planning the scope of testing for various laws of run-to-failure distribution are proposed on the basis of nondiscardability of expensive objects. The study results are recommended for use in creating complex engineering systems.

在开发原型设计和测试过程中达到工程系统高可靠性和安全性的现代诊断技术和数学模型

摘要

本文是关于在开发原型的设计和测试过程中达到并确保工程系统中的高可靠性和安全性的。提出了一种新的方法和一种计算设计可靠性的技术，同时考虑了两种故障率：恒定的故障率和随时间变化的故障率。考虑到机械部件和金属制品的可靠性的计算，设计可靠性计算的功能由整个操作期间故障安全运行概率的三个组成部分的乘积表示。为达到并确保所需的可靠性和安全性水平而提出的计算模型考虑了控制措施。一种新的方法和技术以及数学模型，基于昂贵物品的不可抛弃性，提出了用于计划各种测试方法的测试范围，以测试从头到尾的分布。建议将研究结果用于创建复杂的工程系统。
