对蜂窝夹层板进行了弯曲与振动试验,测得复合板固有频率与受弯曲载荷情况下的位移,同时通过有限元软件ANSYS采用等效板等效方法,仿真分析得出的预测结果与试验结果对比,吻合良好.验证了通过有限元等效模型来进行仿真模拟的准确性,进而为纤维-纸蜂窝复合板的优化设计提供参考依据.

Two tests based on bend and vibration were carried out in this research.The natural frequency and the displacement of fiber-paper honeycomb sandwich structure are composited by bending load.Meanwhile the equivalent method was adopted through the finite element software ANSYS,the computational results were in good agreement with test.Therefore,this study shows that the finite element equivalent models are reasonable and practical for the optimization design of fiber-paper honeycomb sandwich composites.
