摘要
为了选择更有效的表征空压机轴承性能退化特征指标,提出一种基于博弈论组合赋权法的特征指标选取方法。通过对轴承振动进行时域指标分析及冗余信息预处理,获得轴承时域指标数据集。利用单调性、鲁棒性和趋势性3种特征指标评价方法,分别完成性能特征指标选择。基于此,利用博弈论组合赋权法,对3种特征指标和16种时域指标进行加权,完成轴承性能退化指标的选择,并通过实例验证,说明该方法的有效性。
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.
