Performance Optimization of Composite Constrained Viscoelastic Structure with Stand-off Layer
-
摘要: 本文以一种典型结构作为研究对象, 从约束层、扩变层两方面对其减振处理方案进行优化。通过利用大型通用有限元软件ANSYS, 以固有频率、损耗因子和频率响应曲线作为评价参数, 讨论和分析了影响典型结构动态性能的因素。Abstract: In this paper, a typical structure was taken as the object of study, and the optimization of the vibration reduction was carried out from two aspects:the constraint layer and the stand-off layer. By using the general finite element software ANSYS and with the natural frequency, loss factor and frequency response curve as the evaluation parameters, factors influencing the dynamic performances of the typical structure were analyzed.
