Fuzzy Comprehensive Evaluation of Running Status of Engine Based on Information Fusion of Vibration and Oil Physicochemical Property

Abstract

Based on the vibration information of engine and the physicochemical property information of oil of engine, the fuzzy comprehensive evaluation model of running status of engine is established. According to the evaluation model, the fuzzy comprehensive evaluation method is put forward. By the evaluation method, the evaluation of running status of engine is analyzed by an example. The results show that the fuzzy comprehensive evaluation method based on the information fusion of vibration of engine and physicochemical property of oil of engine is reliable and reasonable.
