摘　　要：基于作者最近对主动约束层阻尼(ACLD)圆柱壳的建模研究基础,通过数值算例进一步研究了电压分布方式对ACLD圆柱壳减振效果的影响,重点放在控制方式以及驱动电压的施加方案上.大量的数值计算表明,在多种外激励下的ACLD圆柱壳,采用环向占优模态控制方案,具有最佳的振动抑制效果,进而提出了环向占优模态控制策略的概念.Based on the authors＇ previous research on the model development on active constrained layer damping（ACLD） cylindrical shell,through a lot of numerical examples,the influence of the driving voltage＇s distribution on the damping effect of ACLD circular cylindrical shells was further studied.And the emphasis was put on the control manner and application scheme for driving voltage.The numerical results show that,by using the circumferential dominant modal control strategy,the ACLD circular cylindrical shell attenuates the vibration better.Furthermore,the concept of circumferential dominant modal control was proposed.
