<p>Elastic modulus reflects the ability of wood to resist deformation. The existing longitudinal vibration method plays an important role in the determination of elastic modulus of wood. To simplify the detection system and facilitate measurement, a novel method for measuring the elastic modulus of wood has been proposed, utilizing the longitudinal vibration excitation and electromechanical admittance (EMA) response of dual lead zirconate titanate (PZT) patches coupled with the specimen. To verify the effectiveness of the proposed method, theoretical derivation, finite element simulation and experimental research were carried out respectively. The theoretical derivation results show that the first-order longitudinal vibration mode frequency of the beam specimen coupled with dual PZT patches can be extracted through the real part of EMA response. Simulation results of six kinds of wood specimens show that the dual PZT patch transducer can effectively excite the first-order longitudinal vibration mode of the specimen, the main peak that corresponds to the first-order longitudinal vibration mode of the specimen exists in the EMA response, and the relative errors of the measurement results are less than 0.35%. The experimental results of nine sorts of wood specimens demonstrate that the relative errors are less than 0.6% compared with the corresponding results measured by the existing longitudinal vibration method. These test results verify the effectiveness of the new method.</p>
