柴油机具有可靠性高、功率大、成本低等优点，在船舶动力系统中有非常广泛的应用。柴油机的工作过程非常复杂，是一个空气动力学、热力学、化学等多学科的综合过程。同时，由于柴油机内部结构件种类和装配精度要求高，海上运行环境恶劣，研究柴油机的可靠性具有非常重要的意义。柴油机中的关键部件包括曲轴、轴承、气缸等，其中，轴承作为主要的承载部件，是柴油机动力系统的关键组成部分。本文研究方向在于分析柴油机轴承的动力学特性，建立一种船舶柴油机的在线式轴承损坏评估和监测系统，提高船舶柴油机的可靠性。
The diesel engine has the advantages of high reliability, large power, low cost, etc., and is widely used in the marine power system. The working process of the diesel engine is very complex, which is a comprehensive process of aerodynamics, thermodynamics, chemistry and other disciplines. At the same time, because of the high requirements for the types and assembly accuracy of the internal structural parts of the diesel engine, and the harsh offshore operating environment, it is of great significance to study the reliability of the diesel engine. The key components of diesel engine include crankshaft, bearing, cylinder, etc. bearing, as the main load bearing component, is the key component of diesel power system. The research direction of this paper is to analyze the dynamic characteristics of diesel engine bearings, establish an online bearing damage assessment and monitoring system for marine diesel engines, and improve the reliability of marine diesel engines.
