摘要: 在结构件上敷加阻尼材料能够实现减振的效果,近年来通过对阻尼涂料的研究,敷加阻尼涂料减振成为一种新兴的减振方法。本文通过激振器进行扫频试验,分别对敷加阻尼涂料、丁基橡胶阻尼层的玻璃钢板振动特性进行研究,对比分析了敷加上述两种阻尼材料后玻璃钢板各阶模态固有频率和阻尼损耗因子以及插入损失,进而得到其振动性能。结果表明,两种方式均可以达到减振的效果,但在玻璃钢板上敷加阻尼涂料对结构整体质量影响较小并且减振效果更加理想。

Abstract: Coating technology refers to the application of coating materials on the surface of structural parts to achieve its anti-corrosion, anti-friction, and thermal barrier functions. In recent years, it has been discovered through continuous in-depth research on coating technology that the application of coating materials on structural parts coatings can achieve good vibration damping effects and have little effect on the overall quality of structural parts. At the same time, the coating layer has the advantages of high temperature resistance, corrosion resistance and high hardness. Therefore, it has gradually become an emerging vibration damping method. The vibration characteristics of FRP coated with damping coating and butyl rubber damping layer were studied, and the frequency and damping loss factor of FRP in each mode after applying the above two damping materials were compared and analyzed. The results show that applying damping paint on the GRP plate can achieve a better vibration damping effect.

Key words: butyl rubber, damping coating, composite structure, vibration performance, modal strain energy
