To evaluate the load taken by the ship’s frame structure from water thrust and load from waves.
Thrust from water and the wave loading is important loading parameters in evaluating and optimizing the structural frame of a ship. Quadrant’s team performed one-way FSI analysis to accurately find the drag, vertical, and lateral forces on the hull of the ship structure without expensive testing and physical prototyping.
One-way FSI CFD analysis helped to find the unknown parameters including the forces on the outer surface of the ship as well as the wave profile at a particular speed of the ship. Also, the pseudo transient analysis performed to compute the forces during the start and stop of the system which helped to evaluate the loads when accelerating and stopping the system.
After the CFD analysis, a one-way coupling of the CFD system and FEA system were performed which helped to accurately map the pressure points on to the hull of the ship assembly. This method has helped significantly reduce the total time of analysis setup and improved the accuracy of the simulation. The hull has been designed with composite and internal aluminum welded structure, hence composite and lay-up profiles were set up and the CFD loads were mapped on to the outer surface to perform an accurate analysis of the system.
