摘要
加筋薄壁结构经常被应用在建设工程中,并在单个结构的基础上组合成复杂结构,了解这种结构的振动声辐射理论能够为减振降噪性能的提高和加筋薄壁结构的优化奠定理论基础。为此,本文分析了结构振动和声辐射之间的关系,以及薄壁结构和声腔耦合效应,并以金属外壳模板耦合振动及声辐射为例分析了振动声辐射理论在加筋薄壁结构中的应用。
Reinforced thin-walled structures are often used in construction projects and combined into complex structures on the basis of a single structure.Understanding this structure's vibration-acoustic radiation theory can lay a theoretical foundation for the improvement of vibration-reducing and noise-reducing performance and the optimization of reinforced thin-walled structures.Therefore,in this paper,the relationship between structural vibration and acoustic radiation,and the coupling effect between thin-walled structure and acoustic cavity are analyzed,and the application of vibration-acoustic radiation theory in reinforced thin-walled structures is analyzed by taking metal shell template coupling vibration and acoustic radiation as example.
