机敏约束层阻尼减振板耦合系统有限元模型

针对机敏约束层阻尼减振板结构，考虑到粘接层、压电层、阻尼层、基层结构的耦合运动及位移协调关系，结合压电学理论、有限元理论以及粘弹性材料阻尼性能的滞弹性位移场模型，建立了耦合系统的有限元动力模型，该模型可适用于含SCLD结构的任意复杂系统的振动建模研究。以局部覆盖SCLD结构的对边约束钢板为研究对象，进行了结构动力学参数理论计算、ANSYS模态分析与模态实验研究，结果表明：理论分析与实验结果及ANSYS分析能较好吻合，充分证明了建模方法的有效性。

Finite element model of coupled systems for vibration reduction plates with smart constrained layer damping

Considering the relationships of coupling movement and compatible displacement among bonding layer, piezoelectric layer, damping layer, and base structure, a finite element dynamic model of coupled systems for vibration reduction plates is established. The model combined with piezoelectric theory, finite element theory and ADF model of viscoelastic damping material can be suitable for vibration model of complex SCLD structure. The dynamics parameters for clamped-clamped steel plate with partially treated smart constrained layer damping are obtained by theoretical calculation, ANSYS modal analysis and modal experiment. The results show that theoretical values are closer to the test results and ANSYS analysis, and the methods proposed is more accurate and effective.
