|Title:||Investigating lubrication properties using pulse-echo ultrasound technique||Authors:||Imad, F.
|Issue Date:||2013||Journal:||Proceedings - 2012 IEEE International Conference on Control System, Computing and Engineering, ICCSCE 2012 2013, Article number 6487135, Pages 166-170||Abstract:||This paper presents a technique that utilizes ultrasonic puls-echo method to determine insufficient lubrication in static mechanical components and assemblies. Due to prolong static in-operation of such systems as spring actuated circuit breakers (CB) the lubricants/grease in the actuation mechanism dries up resulting in sluggish response. Since these systems remain static they don't emit any acoustic signals. Therefore active pulse-echo ultrasonic testing method is proposed to determine the lubricant condition. In the proposed method wavelet analysis is used to de-noise the signal and extract data about lubricant condition. The extracted features from different samples is be used to develop a fuzzy inference system to define the lubricant condition. © 2012 IEEE.||DOI:||10.1109/ICCSCE.2012.6487135|
