實驗分析結果表明，該方法對齒輪的表面局部損傷故障的早期診斷和斷齒故障早期診斷十分有效，可以準確地辨別出有故障齒的位置，為齒輪故障診斷提供了一種有效手段。 -
The main contents of this thesis include : ( 1 ) summarize and analysis of the theories on vibration transmission through rolling element bearings ( 2 ) based on the threshold setting and signal ’ s statistical approach, a method for solving the problems of denoise was developed ( 3 ) using sparsity and clustering, the method and hypotheses for underdetermined blind source separation was studied ( 4 ) the method based on potential function clustering was given for underdetermined blind source separation of noisy signals based on the assumption that the input distribution is sparse and the mixture procedure is linear, the attenuation matrix and the delay matrix were estimated by clustering. the approach was experimentally illustrated for the case of m = 2. the separation of the signals from bearing test bed proved that the given methods are available and reliable
