Acoustic Emission Detection Of Early Stages Of Cracks In Rotating Gearbox Components, Dan Xiang Jan 2016

Acoustic Emission Detection Of Early Stages Of Cracks In Rotating Gearbox Components, Dan Xiang

Review of Progress in Quantitative Nondestructive Evaluation

Many critical, highly loaded rotating gearbox components have fast crack propagation rates. Early detection of cracks in gearbox is critical to mitigating the risk of catastrophic failure. Acoustic Emission (AE) techniques have proven to be capable of continuously monitoring the crack initiation and propagation [1-3]. Due to the long distance of AE signal propagation from the AE sources to the sensors installed in the housing, the AE signal suffers from severe attenuation and noises. Accurate AE signal classification technology that is capable of extracting the true AE signal out of background noises generated by the surrounding environment of a gearbox ...
