摘要
针对机—电阻抗法在结构健康监控中应用研究的逐渐深入和目前普遍使用的阻抗分析仪的诸多缺点,设计了一种基于阻抗测量芯片AD5933的压电阻抗分析仪。与当前普遍使用的阻抗分析仪相比,该阻抗分析仪具有体积小,便于携带和在外场使用,而且成本低廉的优点。
As the research on the application of electro-mechanical impedance method （EMI） in structure health monitoring goes deeper and deeper, and aiming at the shortcomings of impedance analysis instruments widely used at present,a piezoelectric impedance analysis instrument was designed based on AD5933, a high precise impedance converter chip. Compared with the impedance analysis instruments widely used at present, this instrument is small, portable and cheap.
