摘要/Abstract

摘要： 由于超声导波的多模态特性和频散特性,实际检测时在同一激发频率下存在多种模态的混合信号,影响导波检测的灵敏度。针对上述存在的问题,在建立导波频散信号的数学模型的基础上,提出一种基于导波基函数投影变换的单模态超声导波提取方法。首先根据频散传递函数建立各模态导波信号的数学模型,将各模态导波信号构建为一组导波模态基,之后,以模态基函数为投影变换核,对接收信号进行投影变换,从而实现多模态混叠信号中单模态导波信号的提取。通过对板中的Lamb波S₀、A₀和A₁混合模态仿真和实际信号处理试验表明,提出的方法无需频散补偿即可实现多模态混叠信号中单模态导波信号的有效提取。

Abstract: A method is proposed to address the multimodal and dispersive nature of ultrasonic guided waves in practical detection scenarios, where mixed signals with various modes are present at the same excitation frequency, affecting the sensitivity of guided wave detection. Based on the mathematical modeling of guided wave dispersion signals, a single-mode ultrasonic guided wave extraction method is introduced using guided wave basis function projection transformation. Initially, mathematical models for each modal guided wave signal are established using the dispersion transfer function. These modal guided wave signals are then formulated into a set of guided wave mode bases. Subsequently, employing the mode basis functions as the projection transformation kernel, the received signals undergo a projection transformation, enabling the effective extraction of single-mode guided wave signals from the superimposed multimodal signals without the need for dispersion compensation. Simulation and experimental signal processing involving Lamb waves and mixed modes on a plate demonstrate the efficacy of the proposed method in achieving the extraction of single-mode guided wave signals without requiring additional dispersion compensation steps, thereby simplifying the ultrasonic guided wave detection process and enhancing sensitivity to guided wave signals.
