纸蜂窝夹层板主共振频率的影响因素
|
摘要
目的研究芯层结构因素和静应力因素对纸蜂窝夹层板-质量系统主共振频率的影响。方法采用正弦振动试验测试纸蜂窝夹层板-质量系统的振动传递特性,分析不同静应力作用下不同蜂窝芯的纸蜂窝夹层板-质量系统的主共振频率变化规律。结果纸蜂窝夹层板-质量系统的主共振频率在150～350Hz之间;蜂窝芯结构及芯层材料影响纸蜂窝夹层板的刚性,从而影响系统的主共振频率;载荷质量变化引起静应力的变化,也会影响系统的主共振频率。主共振频率均随蜂窝胞元边长、纸板厚度、芯纸定量及静应力的增大而降低。结论可为纸蜂窝夹层板的振动传递特性研究提供基础,有助于不同材质蜂窝夹层板的优化设计。
The work aims to study the influences of the structure of honeycomb core and the static stress on the main resonance frequency of the paper honeycomb sandwich plate-block system. The vibration transmissibility of the paper honeycomb sandwich plate-block system was measured by sine vibration test, and the change rules of the main resonance frequencies of paper honeycomb sandwich plate-block system with different honeycomb cores under different static stresses were analyzed. The main resonance frequencies of the paper honeycomb sandwich plate-block system varied from150 Hz to 350 Hz. The structure and material of honeycomb core had influence on the stiffness of paper honeycomb sandwich plate, which changed the main resonance frequency of the system. The change of block mass caused the change of static stress and affected the main resonance frequency of the system. The main resonance frequency decreased with the increase in the cell length of honeycomb, the paperboard thickness, the core paper grammage, and the static stress. A foundation is provided for the research of vibration transmissibility of paper honeycomb sandwich plate, thus promoting the optimization design of the honeycomb sandwich plates with different materials.
