摘要/Abstract

摘要：

噪声水平是现代飞机封闭腔室设计的重要指标，设计中单纯地对壁板进行加肋处理虽能显著降低噪声但会大大增加结构质量，为此对由封闭腔室构成的结构-声耦合系统进行了减重降噪优化研究。基于结构-声耦合有限元模型，利用有限元软件ACTRAN计算了频谱加载时舱内的声压响应。通过试验对简化处理及数值计算进行了验证，并修正了相关模型参数。为了降低结构质量，以加强肋为边界对舱门壁板进行了分区，通过对各个区域壁板厚度及肋条截面积的优化设计，使系统动刚度分配更趋合理，降低了声辐射能量以及结构-声腔的耦合性，从而实现了在满足噪声约束条件下减轻结构质量的目标。本文的工作对实际工程中由加肋壁板所构成的类似结构的减重降噪设计有着较好的工程指导价值。

Abstract:

Noise level is an important index in closed chamber's design of modern aircraft; by using stiffeners traditional design can reduce noise effectively but results in much heavier structures. Thus, an optimization approach of the structural-acoustic coupling system composed of an aircraft equipment bay is studied aimed at mass reduction under noise constraint. A structural-acoustic coupling finite element model is created; by using the finite element software ACTRAN, the acoustic field in the equipment bay can be calculated, which is then verified and amended by experiments. To reduce structure mass of the equipment bay, the cabin door panel is divided into several areas with internal stiffeners as their boundaries. By conducting the optimization of stiffener sections and the thickness of each area, the total mass of the structure drops substantially. Accordingly, the dynamic stiffness of the structure is better distributed, which reduces the acoustic radiation energy and ultimately reduces the noise within the closed chamber. The work of this paper has important guiding significance in practical engineering, especially in similar structural-acoustic coupling system enclosed by thin plate with stiffeners.

Key words: acoustic radiation, structural-acoustic coupling, FEM, noise prediction, structure optimization
