Modeling and Characteristics of Lateral Bending Vibration for Helicopter Tail Drive Shaft during Maneuvering Flight
This paper proposed the description method of spatial motion for helicopter maneuver flight,and used the extended Hamiltons principle to establish the lateral bending vibration model of the helicopter oblique tail drive shaft.of which the horizontal shaft is a special case.The effect of spatial maneuver flight on the vibration characteristics of the tail drive shaft has discussed by the combination of mathematical model and numerical simulation.The study results reveal that the spatial maneuvering flight of helicopter will produce additional stiffness effect,damping effect and external excitation force on the bending vibration which may change the center position and size of the motion orbit of the tail drive shaft.
