SIMULATION AS A DESIGN AID FOR RIDE CONTROL SYSTEMS
As the Surface Effect Ship (SES) travels across the sea supported on a cushion of air, changes in cushion pressure occur as waves pass through the cushion. These pressure produce accelerations which are transmitted to the ship resulting in a decrease in ride quality. The accelerations can be reduced and the ride quality improved by regulating the flow of air into or out of the cushion, thus maintaining a constant cushion pressure. The system which provides this regulation is referred to as the Ride Control System (RCS). A RCS offers the potential for significantly reducing vertical accelerations but the use of such systems result in some decrease of operating efficiency. Accordingly, ride quality criteria based on general health, performance, and comfort considerations are required in order that an intelligent tradeoff between ride quality and other factors can be made. The Surface Effect Ship Project (PMS304) has been pursuing the development of such ride criteria for use in the design of 2000-ton and larger SES using a moving body simulator, predicted ship motion, and simulated tasks. Initial simulations were performed using the Marshall Space Flight Center, Huntsville, Alabama six-degree-of-freedom motion generator and a four-place cab. More recent simulations have used the Office of Naval Research three-degree-of-freedom motion generator at Goleta, California and a two-place cab.
