摘　　要：基于振型组合的思想,提出一种确定网架结构中粘滞阻尼器合理安装位置的方法,通过建立平板网架,对比分析了四种阻尼器布置位置的减震效果,得到了阻尼器在网架结构中的合理布置方式,验证了该判定方法的有效性。Based on the idea of modal combination,a method for determining the reasonable installation location of viscous dampers in the space truss structure is put forward. A flat space truss structure is established and comparative analysis of damping effect of four kinds of working conditions is made,concludes the reasonable layout approaches for the damper in wire frame structure,the effectiveness of this method is verified.

关 键 词：振型组合 平板网架 阻尼器 安装位置
