摘　　要：基于Ｍｉｎｄｌｉｎ 板理论，从圆盘动力学方程出发，在粘弹性材料本构关系基础上，讨论柱面波在圆盘粘弹性波导吸振器中传播和耗能规律，并讨论了振动能量耗散率与圆盘几何参数、材料参数及振动波频率的关系．On the basis of Mindlins plate theory, a dynamic equation of waveguide absorber with viscoelastic circular plate is presented. By investigating the propagation and energy dissipation principle on the base of constitutive relation of viscoelastic materials, it is shown that waveguide absorber with viscoelastic circular plate has good effect on vibration damping and the simulation results validate that the energy dissipation ratio is related to parameters of geometry, material and traveling wave frequency.
