Abstract
In the present paper, identification of dynamic sensing characteristics of macrofiber composite (MFC) and polyvinylidene fluoride (PVDF) is carried out via experimental investigation. As a first step, basic characteristics and operating principles of MFC and PVDF are briefly reviewed. Then, a clamped aluminum beam structure is prepared and experimental setup for vibration signal test is established with shaker system. Both MFC and PVDF are attached on the top and bottom surface of the beam structure, respectively, and connected to data acquisition system. In order to verify the operating bandwidth, frequency responses of the smart beam structure are obtained from 0Hz to 5 kHz under sine sweep excitation. For the identification of dynamic sensing characteristics, experiments for linearity, durability, and robustness are conducted. It is observed that both MFC and PVDF have excellent sensing performance in measuring dynamic response and monitoring structural vibration.
