Advances in vibroacoustic research of stiffened composite plates and sandwich composite plates

复合材料加筋/夹层板壳结构在众多工程领域结构物中已得到广泛应用,研究其声振特性对于指导工程设计具有重要意义。本文对国内外复合材料加筋/夹层板壳结构声振特性的研究进行回顾、梳理和归纳,并探讨各种研究方法的适用性,以及未来的研究趋势。综述结果表明:解析与数值相结合的研究方法兼具灵活性和高效率,是研究声振特性的有效方法,也是重要的发展方向;新材料的应用给研究带来了新变化,增大了结构动力学和声学的设计空间;现有的分析方法可以模拟出结构的任意边界条件而无法还原实际边界条件,因而需要结合试验研究作为支撑。

Stiffened composite plates and sandwich composite plates is widely used in many engineering fields. The study of its vibroacoustic characteristics is instructive for its design. In this paper, the vibroacoustic research of stiffened composite plates and sandwich composite plates is reviewed as well as various research methods used in these research, the trend of future research on the vibroacoustic research is also pointed out. The results show that the semi-analytical numerical method is flexible and effective to vibroacoustic research, and it is future trends of the similar studies. The application of new materials brings new variables to the vibroacoustic research, in the same way, the application of these materials increases the design potential of the structure in the field of dynamics and acoustics. The actual boundary conditions of the structure can not be simulated by using the method of simulation calculation and theoretical calculation, it is necessary to study the boundary conditions by experiment.
