Abstract:

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.
