Description
Suspension ships belong to a novel ship type that employs a suspension system as part of the ship’s body. Suspensions used in land vehicles are well-known for their abilities of enhancing land holding performance and isolating shocks to improve ride comfort. The adoption of suspension systems in ships aims to achieve similar functions. However, it is important to note that the ocean wave surface is more complex than land road profiles, making the design of ship suspensions considerably challenging.
Typically, a floating rigid body has six degrees of freedom. By connecting it to another rigid body, the total degrees of freedom can increase up to twelve. The design of suspension linkages should both constrain certain motions that could pose dangers to the ship and allow for other motions to be controlled to enhance ride comfort.
One critically important aspect in ship design is the stability characteristics of suspension ships. The distribution of mass within the suspended body, the suspension system itself, and the hull all have a significant impact on the ship’s center of gravity and hence the metacenter height. Additionally, other factors influencing the ship’s stability include the loaded height of the suspension system (which is the height between the suspended body and the hull when the ship reaches static equilibrium) and the placement location height (which is the height of the suspension bottom relative to the keel of the ship).
In this study, we investigate the influence of the mass ratios, loaded heights, and placement location heights on the initial transverse stability of suspension ships while keeping the total weight of the ship and the center of buoyance constant. We also discuss design proposals for suspension ships in both monohull and catamaran configurations.
