摘要
Abstract
To study the performance parameter deteriorates of engine,a method of engine module performance parameter residuals series was developed.Sensitivity of measured parameters to component performance parameters was analyzed based on engine model,component performance parameters which could denote engine abrupt variation were optimized.The performance parameter residuals series was gained by means of the foundation of multi-linear regression model.Engine abrupt variation was researched by analysis of performance parameter residuals time series,combining with the algorithm,abrupt time could be confirmed,which provided reference for engine maintenance.关键词
