飞机副翼采用碳纤维/环氧,Nomex纸蜂窝夹芯壁板与碳纤维/环氧实心梁、肋空间组合结构在国内还是首次。作者结合某改型机副翼的设计进行了应力应变有限元的分析计算,编制了一套通用于翼面的夹心壁板组合结构八节点等参元计算程序,按用于微机IBM-PC及其兼容机编制,从而使计算费用大为降低,将计算结果与原结构数据分析比较证明,计算所得的应力应变分布规律正确,适用于高性能的新型复合材料夹芯结构计算。
Aircraft ailerons use carbon fiber/epoxy, Nomex paper honeycomb sandwich panels and carbon fiber/epoxy solid beams, rib space combination structure is the first time in the country. Combining with the design of a modified aircraft aileron, the author analyzed and calculated the stress-strain finite element, and compiled a set of eight-node isoparametric calculation program for the sandwich structure of the sandwich panel commonly used for the airfoil, which was used in the computer IBM-PC and Compatible with the establishment of the machine, so that the computational cost is greatly reduced, the calculation results and the original structure data analysis and comparison prove that the calculated stress and strain distribution law is correct, suitable for high-performance new composite sandwich structure calculation.
