摘要: 一、引言 直升机的旋翼不仅是直升机的操纵面,还是直升机的升力面。因此,直升机的性能品质及安全性等等无不与旋翼桨叶及其操纵系统相互作用的耦合动力特性有关。且不难明白在飞行条件下,它即取决于操纵系统中随频率或时间而变化的刚度特性也即动刚度特

Abstract: According to the reference, this paper gives the calculation of dynamic stiffness characteristics of Z-6 helicopter longitudinal control system. In the paper, the method of establishing complex matrix. equation of a multi-freedom mechanical model and the procedure of calculating dynamic stiffness and eigenvalues for a real mechanical hydraulic flight control system are presented. The est results are also given.
