摘要：
在蜂窝板结构有限元仿真分析中,一般将蜂窝板等效成实心板进行计算,来获取某型蜂窝板等效弹性模量。采用LMS Test.lab声振试验系统测得模态试验结果,运用ANSYS Workbench有限元软件进行模态调参仿真分析。模态调参仿真结果与模态试验结果相比,前4阶固有模态频率误差在5%以内,且对应各阶模态振型非常一致。试验获得的该蜂窝板的等效弹性模量E=55 GPa,在动力学仿真中能够真实反映蜂窝板实际结构的动态特性。

Abstract: In the finite element analysis of the honeycomb panel structure, the honeycomb panel was generally equivalent to the solid plate for calculation. The modal test results measured by the LMS Test.lab sound and vibration test system were carried out modal adjust parameter simulation analysis by using ANSYS Workbench finite element software. Compared modal parameter simulation results with the modal test results, the first 4 inherent in the modal frequency error less than 5%, and corresponding to each mode shapes were very consistent. The equivalent elastic modulus by the honeycomb plate test was E=55 GPa. It really reflected the dynamic characteristics of the honeycomb panel actual structure.
Keywords: honeycomb panel; equivalent elasticity modulus; modal test; adjust parameter
