Research on motion and load response of ultra-slender trimaran in irregular waves
英文摘要:Taking an ultra-slendertrimaran as an example, it's motion and load response in irregular wave has been computed. The results show that the side hulls with light displacement slightly affect the distribution of the vertical bending moment and shear forceas the center of gravity for the trimaran shifts aftwards slightly. The results also indicate that the trimaran can be considered as a beam simply supported at both ends along the ship breadth. The transverse bending moment can be estimated to assess the connection structure of the mail hull and side hull. Different speeds result in different draughts. The calculation demonstrates that the speed of 29 kn is the best for the specific ship.
