加筋平板结构在工程、建筑等领域中有广泛应用。本文提出了一种加筋平板结构声振响应模型,可同时考虑任意边界条件和任意加筋参数,并快速计算结构的振动特性及声传递损失。基于该模型并结合低频噪声评价指标,本文对加筋型平板建筑结构的低频隔声性能进行了综合分析,研究结果表明:建筑结构的边界条件和加筋参数都对建筑结构的隔声性能有重要影响,本文所提模型及分析方法能有效分析这些影响,并有助于加筋型建筑结构的优化设计。
Reinforced plate structure in engineering, construction and other fields have a wide range of applications. This paper presents a model of stiffened plate structure acoustic vibration response, which can simultaneously consider any boundary conditions and any stiffened parameters, and quickly calculate the vibration characteristics of the structure and the acoustic transmission loss. Based on the model and the low frequency noise evaluation index, the paper analyzes the low frequency sound insulation performance of the reinforced slab-building structure comprehensively. The results show that the boundary conditions and the reinforced parameters of the building structure have sound insulation properties to the building structure Important influence, the model and analysis method mentioned in this paper can effectively analyze these influences and contribute to the optimization design of reinforced building structure.
