考虑横向剪切的双层板架临界载荷计算 总被引：1，自引：0，他引：1
本文考虑横向剪切效应,建立了一种计算双层板架结构临界载荷的方法：将复杂的双层板架结构从其相邻结构中分离出来,用弹性约束计及相邻结构的影响,用正交异性板的方法描述其力学特性,用能量法求解双层板架结构临界载荷。结果表明该方法可靠,尤其适合在工程方案的论证阶段应用。 相似文献

IntroductionThe conventional passive constrained layerdamping (PCLD) treatments[1～ 3] are applied tomachines and structures widely over the lastcentu-ry because they are reliable and simple,however,they are not intelligent. Once the damping treat-ments are installed,they can not be adjusted andcan not adapt themselves to changeable environ-ment.Recently,active damping has received in-creasing attention in the aeronautic and astronauticindustries because of its significant and adjustabledamp… 相似文献
