摘要
The paper is devoted to the determination of the optimum wavelet-function for the analysis of impulses in vibration signals. The algorithm for the evaluation of their parameters based on the single-degree-of-freedom-system response model has been proposed. Limitations of using the algorithm are valued from the level of the relative error 10% under the influence of noise and harmonic components. (C) 2004 Elsevier Ltd. All rights reserved.
