目的 研究不同类型异形网格包装板在振动声辐射方面的性能差异,为包装板结构减材降噪技术开辟新设计路径。方法 以开圆形孔的铝合金包装板为对象构建板结构模型,基于多样化孔径排布方案开展结构动力学分析,运用有限元方法解析异形网格包装板的动力学特性及声辐射特性,采用模态叠加法对比振动传递结果和声辐射级结果。结果 随着孔径增大而结构固有频率呈降低趋势;大孔网格包装板整体等效辐射声压级（ERPL）表现优异;外向内渐变孔径设计的网格板的声辐射特性与大孔径板动力学特征相似,其中振动传递与声辐射级遵循结构共振频段范围内的动态响应变化趋势相一致。结论 该类网格包装板在竖直基础激励下主要呈现竖直向上的振动模态,在其他方向激励下振动传递也具有良好的稳定性;通过有限元法揭示了此类板结构的声辐射布局演化规律,为同类板结构减振降噪设计与优化提供了参考。
Abstract
The work aims to investigate the differences in vibration and sound radiation performance among different types of irregular grid packaging boards, to pioneer new design pathways for material reduction and noise reduction technologies in packaging board structures. An aluminum alloy packaging board with circular holes was selected as the research object to establish a board structure model. The structural dynamic analysis was conducted based on diverse hole diameter arrangement schemes. The finite element method (FEM) was employed to analyze the dynamic characteristics and sound radiation performance of the irregular grid packaging boards, and the modal superposition method was used to compare vibration transmission results and sound radiation level outcomes. The natural frequency of the structure showed a decreasing trend with the increasing hole diameter. The large-hole grid packaging board exhibited excellent overall Equivalent Radiated Sound Pressure Level (ERPL). The sound radiation characteristics of the grid board with an outward-inward gradient hole diameter design were similar to the dynamic characteristics of the large-hole board. Among them, vibration transmission and sound radiation levels followed the same trend as the dynamic response within the structural resonance frequency band. This type of grid packaging board mainly exhibits vertical upward vibration modes under vertical base excitation, and also maintains good stability in vibration transmission under excitation in other directions. The finite element method reveals the evolution law of sound radiation distribution of such board structures, providing a reference for the design and optimization of vibration and noise reduction in similar board structures.
