| 摘 要： | 对增设粘滞阻尼器的局部双层网壳结构进行减振分析,探讨了阻尼器位置、数量、阻尼系数等不同参数对局部双层网壳结构减振性能的影响,分析了不同参数阻尼器的减振效果.计算分析表明:结构阻尼单元的阻尼系数越大,结构的减振效果越好;设置的阻尼器数量越多,结构减振效果越好;对于局部双层球壳结构,斜向设置粘滞阻尼器的效果最佳.

| Abstract: | The aseismatic properties of a partial double layer reticulated shell structure are analyzed in this paper.The effects of damping position,damping number and damping coefficient on dynamic performance of the structure are investigated.The efficiency of the viscous damper system is discussed.The numerical results show that with the increase of damper number and damping coefficient,the dynamic property of the structure improves.It is better for partial double-layer spherical reticulated shell structures to se... |
