This book  presents vibration methods for diagnosing and  prognosing mechanical faults in electric motors and  washing machines. This includes pre-processing of  raw vibration data for reducing measurement noise,  such as speckle noise occurring when optically rough  surfaces are measured by Laser Doppler Vibrometer  (LDV). New algorithms for speckle noise reduction  are presented, including kurtosis ratio and optical  level thresholding. Application to real LDV data  (measured on production line by AEA srl, Loccioni)  shows that these algorithms improve detectability of  mechanical faults by enhancing envelope and order  spectra. The book gives practical examples how to  successfully combine classical methods (cepstrum,  CPB spectrum, order tracking), as well as recent  algorithms based on wavelet transform. The book  presents findings of accelerated lifetime tests  suggesting that motors and gearboxes possess a great  potential for reuse. Proposed methods can be  integrated into remaining life estimation  methodologies.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843359115\"\u003e\u003ch3\u003eDiagnostics of Electric Motors and Household Appliances using Laser Doppler Vibrometer\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843359115","offer_id":39497039904861,"sku":"9783843359115","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e93c10bf-1405-488d-9aad-493976f90059.jpg?v=1769148741","url":"https:\/\/shop.autorenwelt.de\/en\/products\/vibration-fault-diagnostics-for-quality-control-and-component-reuse-von-jiri-vass-robert-b-randall-und-radislav-smid","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
