摘要 基于回传射线矩阵法(RMM)提出了修正的电阻抗理论模型,使得电阻抗信号能与含裂纹结构的各物理参数定量联系起来。分别用Timoshenko梁理论和经典杆理论描述门式框架各结构元件的弯曲振动和轴向振动,结构裂纹模拟为具有一定刚度的转动弹簧。对于粘贴有压电片的结构元件,把它作为压电片-粘结剂-主体结构这一耦合结构系统加以考察,最后推导出包含了结构裂纹信息的电阻抗的解析表达式。基于该模型,从压电片中提取的电阻抗信号可以有效识别门式框架中的裂纹。 A modified model combining electro-mechanical impedance(EMI) technique with reverberation-ray matrix method(RMM) was presented to quantitatively relate crack parameters with piezoelectric signatures for structural health monitoring.The structural members of portal frames were modeled as Timoshenko beams for flexural motion and as the classical longitudinal rods for axial motion as well as the cracks were treated as massless rotational springs.For a structural segment with surface-bonded PZT wafer,a coupled system was considered.Then,an analytical expression of electro-mechanical impedance involving information of cracks was derived.By using the method,the EMI signatures extracted from the PZT wafers can be used to detect cracks in a portal frame.
