| 摘 要： | 受到啄木鸟敲击树干找虫子等敲击现象的启发,论文针对梁式结构提出了一种敲击扫描式损伤检测方法.基于对敲击扫描过程的理论探讨,我们得到了该方法的灵敏度表达式,从而为该方法找到了可靠的理论基础.数值模拟和简单实验表明,该方法不但简单易行,而且在有干扰的环境下也可以有效地检测出结构的损伤.

| Abstract: | Inspired by the hunting behavior of woodpeckers,a Tap-scan damage detection method for beam structures is proposed in this paper.The sensitivity discussions of this method are carried out based on the analytical solution of the tap-scan process.Thus,establishes a solid theoretical foundation for this method.Numerical and experimental results demonstrate that this method is not only easy to implement,but also can reliably detect the structural damage in noisy environment. |
