摘　　要：就满足固有频率和振型要求的翼面结构动力学设计问题提出了一种有效的工程解决方法,并且应用于实际的型号设计。试验结果表明,机翼结构的设计满足了设计要求。其解决过程对于新机设计或用复合材料替换金属结构的等效刚度设计均有重要的指导意义。An effective engineering solution is developed to meet the requirements of natural frequencies and positions of nodal lines for composite wing structure dynamics design, and apply to the actual aircraft design. The results of the experiment show that the design of the wing structure satisfies the design requirements. The solving process is of important instructiveness to new aircraft design or stiffness equivalent design in replacing metals with composites.
