Abstract
A method is provided for quantifying design parameters for a moving mass ship roll stimulation system given a maximum angle of roll &thgr; to be induced for a ship, a righting moment R per degree of list for the ship, a natural roll period T , a damping ratio &zgr; for the ship and a center of gravity for the ship. A total induced moment expression at the natural roll period T is determined for the moving mass ship roll stimulation system as a function of a plurality of design parameters therefor. The total induced moment expression is equated to 2&zgr;&thgr; R and values for the design parameters are selected to satisfy the equality.
