摘　　要：以变截面梁类粘弹性波导吸振器动力学模型为基础 ,讨论了开槽圆盘粘弹性波导吸振器的能耗与波的频率、盘的材料参数、结构参数等之间的关系 ,并应用机械阻抗理论讨论了导出杆与开槽圆盘的阻抗匹配问题 .计算机仿真曲线表明 。Based on a dynamic model of viscoelastic waveguide absorber with changeable section, the principle of energy dissipation is deduced concerned with parameters of wave frequencies, structures, materials and so on. With the aid of mechanical impedance theory, the impedance match of circular plate and its link is discussed. The stimulant curves show that if the parameters of circular plate and its link are perfectly chosen, the effect on vibration damping can be the best.
