摘　　要：导出了自感知主被动阻尼控制梁结构的振动控制方程。引入速度负反馈形成闭环控制 ,对被动控制和主被动控制的控制效果进行了分析比较。分析了粘弹层、压电层厚度和压电片位置等结构参数变化以及材料参数变化对控制效果及结构频率的影响。The equations of motion governing the vibration of a beam with a partial self sensing active constrained layer damping treatment (SACL) are derived by application of the extended Hamilton principle. The mathematical models based on the assumed modes method and a closed loop velocity feed back control law are developed to describe the flexural vibration dynamic behaviors. The influence of the bonding layer thickness and material properties, piezoelectric layer thickness, placements and feed back control parameters on the vibration suppression are investigated. Some design considerations for pure passive and self sensing active constrained layer damping are discussed.
