Abstract:The mechanical impedance properties of a composite bar are investigated in this paper.The measuring principle and the measuring layout are described.The composite bar is tested on the impedance platform facility.It shows that theoretical results coincide with the experimental data when excitation frequency is higher than 100Hz, which also validates the measurement method.
Keywords:composite bar  mechanical impedance  measurement
