| Abstract: | The simulation experiment of acoustic emission(AE) technique for gear fatigue fracture testing is provided.A set of gear tooth load-bearing equipment is designed.And the AE testing system is built.During the procedure of the experiment,the noise-disturbing problems and the noise-eliminating method are analyzed.After the AE signals are acquired,the wavelet packet analysis is employed in obtaining the characteristic of the gear fatigue fracture spread.The soft demodulation method is applied to identifying the AE source. |
