摘要
目的针对蜂窝纸板的振动防护性能,研究不同结构和材料参数的蜂窝纸板振动传递特性的有限元仿真分析方法。方法利用有限元软件Abaqus/Standard建立蜂窝纸板-质量系统模型,设定2种蜂窝纸板,分别具有不同的面纸材料参数和蜂窝胞元边长。仿真分析蜂窝纸板的振动传递特性,并对其进行实验验证。结果通过仿真和实验得到了蜂窝纸板的振动传递率-频率曲线,共振频率的仿真结果与实验值误差小于3.43%,共振时振动传递率的仿真结果与实验值误差小于11.31%。结论利用该有限元仿真方法,能够获得不同结构和材料参数的蜂窝纸板的振动传递特性。仿真分析结果表明,面纸定量对蜂窝纸板振动传递特性的影响不大,而蜂窝胞元边长较大的蜂窝纸板,其系统共振频率较小,振动传递率变化不明显。
The work aims to study the finite element simulation analysis method for vibration transmissibility of honeycomb paperboard with different structural and material parameters, with respect to the vibration protection performance of honeycomb paperboard. Based on the finite element software Abaqus/Standard, the honeycomb paperboard-mass system model was established. Then, two kinds of honeycomb paperboards were set up with different liner material parameters and honeycomb cell side length. The vibration transmissibility of honeycomb paperboards was analyzed by simulation and verified by experiments. The vibration transmissibility-frequency curve of honeycomb paperboard was obtained through simulation and experiment. The error between the simulation result of resonance frequency and the experimental value was less than 3.43%, and the error between the simulation result of vibration transmissibility and the experimental value during resonance was less than 11.31%. The finite element simulation method can be used to obtain the vibration transmissibility of honeycomb paperboard with different structural and material parameters. Moreover, the simulation analysis results show that the effect of liner grammage on vibration transmissibility of honeycomb paperboard is small, while the resonance frequency of system of honeycomb paperboard with larger honeycomb cell length is smaller, yet the change of vibration transmissibility is not obvious.
