MOTIONS OF TILT FLOAT VEHICLES IN WAVES,

Abstract

Th non-linear equations of motion for the heave, pitch (or roll) and surge (or sway) motion of a tilt-float supported amphibious vehicle drifting in a seaway are derived. These equations are programmed for an IBM 7090 electronic digital computer and the results of computations which show the effect of various parameters on the heave and pitch response to waves of all significant frequencies contained in a seaway are presented. The principal parameters investigated are the effects of the slenderness ratio of the floats, the vertical elevation of the c.g. of the vehicle, the radius of gyration of the vehicle, the cant angle of the floats, vertical and horizontal damping plates, the geometric arrangement of the floats and wave height (non-linear effect).
