Abstract

This paper presents the research on reliability of high-speed radial marine diesel engine Zvijezda M 504 B2 based on experimental data of malfunctions on the engine and time required for repair. Exploitation reliability and failure intensity were calculated from operational data collected from the engine log book. Results were tested by computer program to determine the relevance of the obtained results. Mathematically calculated reliability model of high-speed radial marine diesel engine Zvijezda M 504 B2 showed continuous increasing function of the intensity of failure and the fact that the reliability of the engine can be reliably approximated by Weibull distribution. Based on the obtained results it has been shown that this distribution, regardless of its complexity, should be used in practice when calculating reliability of engines with similar constant and growing malfunction’s intensity. The conclusion is that proposed distribution enables a better depiction of the observed technical system and the impact of aging of components on the system reliability.

高速径向柴油机开发可靠性结果的研究、处理与分析

本文根据Zvijezda m504b2型船用高速径向柴油机的故障试验数据和维修时间，对该柴油机的可靠性进行了研究。利用从发动机日志中收集的运行数据，计算了开发可靠性和故障强度。用计算机程序对所得结果进行检验，以确定所得结果的相关性。对Zvijezda m504b2型船用高速径向柴油机的可靠性模型进行了数学计算，结果表明，该发动机的可靠性随故障强度呈连续递增的函数，可以用威布尔分布可靠地逼近。结果表明，该分布无论多么复杂，在实际工作中，在计算具有相似常数且故障强度不断增大的发动机的可靠性时，都应采用该分布。结论是，所提出的分布能够更好地描述所观察到的技术系统以及部件老化对系统可靠性的影响。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
