The influence of a moving suspension on the behavior of helicopter underslung loads was investigated both experimentally and analytically. Experimental modelling was achieved using a double pendulum arrangement incorporating three mutually perpendicular translational support stiffnesses. Both experimentally and analytically, the influence of suspension point characteristics on the behavior of the load was shown to be radical. Generic classification of this non-linear system enabled the predominant behavioral features to be isolated.
