Small Sample Competing Failure Model of Cylinder Liners in Diesel Engines

摘要

In order to deal with the small sample problem in practical reliability analysis of the diesel engine cylinder liner, the method and the steps of using support vector machine to build a regression prediction model to eventually develop the competing failure model of diesel engine cylinder liner are proposed. As proposed, more samples are generated by use of the regression prediction model and the quasi maximum likelihood method is used to separately estimate the occurring patterns of two failure models, including abrasion deterioration and pyrolysis. The scientificity and effectiveness of this method was demonstrated through calculation of examples and comparison of results.
