摘要：
A trend removing method based on modified ensemble empirical mode decomposition (MEEMD) was proposed, to solve the trend interference problem existing in blasting vibration tests, and the extensive simulations of analog signals and the case analysis of blasting vibration signal were carried out. The extensive simulations show that the results of the proposed method for sustained vibration signals are close to the results of the existing trend removing methods based on empirical mode decomposition (EMD) or ensemble empirical mode decomposition (EEMD). When the test signals are intermittent, the proposed method can extract the trend more fully, which embodies its superiority and applicability to remove the trend in blasting vibration signal. In the meantime, the reliability of the proposed method in practical application was proved by the case analysis. © 2021, Editorial Department of Transaction of Beijing Institute of Technology.
