摘要
从工程实际出发,将工程算法、特征值法及弧长法3种用于复合材料壁板稳定性计算的方法的特点和计算结果进行了研究比较,并将试验结果与计算结果进行了对比,从中总结了各种算法计算结果的特征、计算精度、优劣点及适用飞机设计的哪个阶段,便于在飞机设计时,根据工程实际合理选用适当算法来达到计算要求,节省研制时间。
From the perspective of engineering practice,research and comparison on characteristics and calculation results of the three methods,w hich are engineering method,arc-length method and eigenvalue analytical method,for stability calculation of composite stiffened panel are presented in this paper. Comparison betw een the results of testing and calculation is also presented,accordingly,characteristics of the calculation results,calculation precision,fitness for use in different aircraft design phases,advantages and disadvantages of various calculation methods can be concluded. Therefore,it w ill be easy to reach the requirement of calculation by choosing appropriate calculation method properly according to engineering practice,and the design time can also be saved.
