Structure Check and Optimization of Small Waterplane Area Twin-Hull Ship Under Transverse Load

The finite element simulation method is adopted to make a strength check on a new type small waterplane area twin-hull ship. The structure strength and stress distribution characteristics of the ship form under transverse load are studied, and the structure optimization design scheme is given, so that the purpose to control the weight strictly is achieved on the basis of ensuring the structure safety. The formed check flow method and optimization design scheme can provide the design and check guidance for the similar ships.
