基于博弈论组合赋权法的轴承性能退化特征指标选择
Selection of performance degradation characteristic indicators of bearings based on game theory combinatorial weighting method
摘要
Abstract
In order to select the characteristic indicator to more effectively characterize the performance degradation of the air compressor bearing,a feature indicator selection method based on game theory combinatorial weighting method was proposed.Through the analysis of the time-domain indicator of the bearing vibration and the preprocessing of redundant information,the time-domain indicator dataset of the bearing was obtained.Three characteristic indicator evaluation methods including monotonicity,robustness and trend were used to complete the selection of performance characteristic indicators.Based on this,the game theory combinatorial weighting method was used to weight three characteristic indicator and sixteen time-domain indicator to complete the selection of bearing performance degradation indicator.The effectiveness of this method was illustrated by example verification.关键词
