玻璃钢约束阻尼复合结构的阻尼特性
|
Abstract:
以玻璃纤维增强树脂作为约束层主要材料、丁腈橡胶为阻尼层、钢板为基板制备约束阻尼复合结构, 运用动态黏弹谱仪和悬臂梁共振法, 研究温度、约束层刚度和阻尼层结构对约束阻尼复合结构减振效果的影响。结果表明:自由阻尼复合板的最大阻尼范围落在阻尼层的玻璃化转变区;玻璃钢约束层能将复合结构的阻尼拓展至阻尼层的高弹态区域, 增加阻尼层厚度可以提高约束复合板的阻尼性能;提高孔隙率同样有利于约束复合板阻尼性能提升;铝板约束层提升作用尤为显著, 然而在海洋环境、干湿交替等强腐蚀场合中, 铝板极易腐蚀而丧失约束功能, 因此在这类特殊场合下耐腐蚀的玻璃钢具有优势。 Constrained-layer damping composite structure was prepared with glass fiber reinforced resin as constrained layer main material, nitrile butadiene rubber as damping layer and steel plate as basic plate. Dynamic mechanical analyzer and cantilever beam resonance method were used to study the influence of temperature, stiffness of constrained layer and the structure of damping layers on damping effect of constrained-layer damping composite structure. The results show that the free damping composite plate exhibits highest damping range when the damping layer is in glass transition region and extends to the high elastic state region when pasted with glass fiber reinforced plastics as constrained layer. Increasing the thickness and porosity of damping layer will improve the damping property of constrained-layer composite plate. The effects of aluminum plate which pasted as constrained layer is particularly significant. Aluminum plate cannot be used as constrained layer because of the serious corrosion in sea-water and dry/wet cycling strong corrosion occasions. Anti-corrosion glass fiber reinforced plastics is preferred under these special occasions. 国防基础科学研究计划(A0320132009)
