A Combination of WKNN to Fault Diagnosis of Rolling Element Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new method for fault diagnosis of rolling element bearings, which is developed based on a combination of weighted K nearest neighbor (WKNN) classifiers. This method uses ...
Application of a Novel Hybrid Intelligent Method to Compound Fault Diagnosis of Locomotive Roller Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To diagnose compound faults of locomotive roller bearings accurately, a novel hybrid intelligent diagnosis method is proposed in this paper. First of all, vibration signals are preprocessed to ...
A Comparative Study on the Local Mean Decomposition and Empirical Mode Decomposition and Their Applications to Rotating Machinery Health Diagnosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Health diagnosis of the rotating machinery can identify potential failure at its early stage and reduce severe machine damage and costly machine downtime. In recent years, the adaptive decomposition ...
Source Contribution Evaluation of Mechanical Vibration Signals via Enhanced Independent Component Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Extraction of effective information from measured vibration signals is a fundamental task for the machinery condition monitoring and fault diagnosis. As a typical blind source separation (BSS) ...
Mechanism of Interior Ballistic Peak Phenomenon of Guns and Its Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The erosion and wear in the gun barrel will get worse with an increase in the number of projectiles fired. Generally speaking, the ballistic performance of the gun, measured through indicators ...
