摘要

运用导纳功率流法，建立了含集中质量负载的梁与板的耦合振动模型，分析了质量负载对耦合系统功率流传递的影响，并通过ANSYS的优化模块，对梁上附加集中质量的质量大小及在梁上的位置进行了优化设计。研究表明：附加质量对耦合系统的功率流峰值有显著影响，影响的程度与梁板的结构参数有关；合理选择附加质量的质量大小及在梁上的位置，可以提高梁式动力吸振器的吸振效果。

Abstract

In this paper, based on power flow theory, the vibration model of mass-loaded beam-plate coupling system is established. The effect of the added point masses of the beam and the parameters of the bean and plate of the coupling system is discussed in detail by numerical simulation. To develop absorption ability of the dynamic vibration absorber, the optimization of added point masses of the beam is carried out in ANSYS’s optimization mode. The results of optimization is feasible.
