Experimental Study on the Stiffened Panels with Constrained Layer Damping Treatments

  • 摘要: 基于试验模态分析,考察船用加强筋板架模型在不同敷设位置,全部进行约束阻尼等处理方式对系统动态特性的影响。试验结果表明:(1)板架表面进行约束阻尼处理后,在不同测点位置,结构表面振动均有不同程度的衰减;(2)阻尼减振作用与激励源传播距离有关,在激励点位置,阻尼减振效果不佳;(3)阻尼减振效果与激励方式、阻尼敷设位置均有一定关系,局部阻尼处理在特定情况下可达到与全部阻尼处理相当的减振效果。
    Abstract: This paper describes experiment investigations of the effect of constrained damping layers on vibration control of ship structural panels. The structural damping effects of different configurations as well as the positioning of exciting points have been investigated. The test results show that:(1) The vibration level of ship structural panels can always be decreased to some exteat after adding constrained damping layers. (2) The picking up distance way from exciting sources have some influence on the damping capacity, near the position of exciting sources, the damping effects perform not well. (3) The effectiveness of damping layers is relevant with the exciting style and positioning of damping layers, local damping layer treatments can obtain a better damping effect than that of whole treatments to target specific vibration mode of structural panel.
