摘要
对碳纤维蜂窝夹层结构的动力学问题进行了深入分析。将碳纤维网格表面等效为正交异性薄板,铝蜂窝夹芯按蜂窝实际受力情况和尺寸大小等效为三维正交异性体,并考虑到为了防止失稳破坏而进行的蜂窝局部加密、碳纤维表板加厚及结构局部加强。所建模型经复杂结构有限元方法分析,结果和试验相吻合,表明等效模型是合理的,方法是正确的。
In this paper,the dynamic analysis of the carbon fiber honeycomb sandwich structure was deeply investigated. The carbon fiber net plate was equivalent to an orthotropic plate, and the honeycomb core was equivalent to a threedimensional orthotropic solid based on the principle of work equivalence. In order to prevent some buckling of the structure, it is important to thicken the part of the carbon fiber plate and densify the core of the honeycomb. Using complex structure finite element analysis, the theoretical prediction conforms with the experimental results very well, the equivalent model is reasonable, and the method is correct.
