摘要:
对自动铺丝带来的变刚度问题研究近期才引起关注,目前还处于探索阶段,变刚度加筋结构的工程应用仍需要大量的机理性探究作为数据支撑。基于分段线性化的离散思想和纤维平移法,使用Matlab/ABAQUS杂交建模法建立变刚度层板有限元模型。考虑材料刚度退化及筋条与蒙皮之间的界面损伤,基于Hashin准则编写的子程序,研究了变刚度蒙皮加筋板在压缩和压剪组合载荷下的承载能力。对比直线铺放加筋板和变刚度加筋板的载荷-位移曲线,证明采用合理的曲线铺丝设计,加筋板的承载能力可以得到显著提高,通过对几种加筋板在上述2种载荷工况下的渐进失效分析,研究了变刚度蒙皮加筋板的失效机理和其对整体承载性能的影响。实验结果表明:采取合理的变刚度蒙皮的方式能够较为显著地提高加筋板的刚度,提高结构的极限承载能力。
