摘要
含裂纹结构由于受到裂纹的削弱,其刚度与不含裂纹的原结构相比有所降低,导致了含裂纹结构的自然频率随裂纹位置和大小的不同而改变。利用神经网络非凡的非线形模拟能力可以模拟出结构自然频率的变化与裂纹的关系,从而可以进行结构的裂纹检测。
The structure containing the crack has a lower stiff than one having no crack, which can cause the frequency of cracked structure to change as the crack's location and sizes change. Uses might ability of manual nerve network, the relation between the change of frequency and the location and sizes of crack can be simulated,and then, the crack can be detected.
