摘要
为解决某大型船舶柴油机气缸套裂纹故障问题 ,利用着色探伤、电子显微镜扫描、能谱分析、化学成分分析等方法对其裂纹进行了研究分析 ;并利用实船测试、有限元分析等方法对该型缸套的温度分布状况、应力状况 ,进行了研究分析 .
To solve cylinder liner crack problem of a certain large marine diesel engine,the crack was studied and analysed being aimed at the cylinder liner which created the crack by means of colouring crack detection,electron microscope scanning,energy spectrum analysis,chemical composition analysis and so on.Also the temperature distribution and the stress condition of the cylinder liner were researched and analysed utilising measurement on board ship and finite element analysis method.Finally the main causes of the cylinder liner crack were synthetically analysed and determined.
