Abstract

Blasting vibration signals are mostly contain noise limited by field conditions, higher requirements are put forward for the performance of noise reduction methods. In order to obtain the real vibration characteristics, the study establishes a joint denoising method based on the improved modified ensemble empirical mode decomposition (MEEMD） algorithm. Firstly, the original signal was decomposed with MEEMD to obtain the intrinsic mode function (IMF), and the IMF was classified with combining the correlation coefficient and sample entropy (SE）-Hurst index. Then, the least mean square (LMS）was used to filter the residual noise in the noisy IMF component to finish signal denoising. The algorithm comparison results show that MEEMD-LMS has better noise reduction performance than complementary ensemble empirical mode decomposition (CEEMD） and fast ensemble empirical mode decomposition (FEEMD）in the simulation experiment. In the case analysis of tunnel excavation blasting, MEEMD-LMS has better noise reduction effect on high frequency noise than MEEMD, and the low frequency spectrum is clearer. The noise reduction model has good applicability.
