    This paper established a mechanical model of a helicopter ground resonance analysis to calculate the equivalent stiffness and damping of the landing gear in the hub center. It is according shimmy hinge overhang amount and the quality of the static and the effective stiffness of the hub center to avoid ground resonance for parameters improved.
