摘　　要：针对复合材料杆试件,从理论上指导了其机械阻抗特性。介绍了机械阻抗测量原理和测量方案,并在阻抗平台上测得了机械阻抗数据。结果表明,激励频率高于100Hz时,理论预测值和试验测量值相差较小,证明了该实验方法的正确性。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.
