摘要
针对复合材料帽型长桁进行了有限元计算和试验研究,得到帽型长桁在轴压载荷作用下的失稳和压损载荷。研究结果表明,有限元模型中若不考虑捻子条则会影响到计算的精度,有限元计算所得的局部屈曲载荷偏保守,该结果为民机复合材料长桁结构设计提供参考依据。
The finite element calculation and experimental study of composite omega stringer are carried out, and the buckling and crippling loads of omega stringer under axial compression are obtained. The results show that the local buckling load is conservative if the noodle is not considered in the finite element model. The results provide a reference for the design of civil aircraft composite material stringer.
