Hull Structure Optimization Research Of 88m Luxury Yacht

For luxury yacht structure optimization research which is few at home and abroad, most research still stay in steel structure optimization research vessel and traditional business on ships. The paper about optimization of hull structure is combined with their actual work experience and the main structural problems encountered focusing on the typical and some sensitive structure using finite element optimization research area. To cooperate with other professional loft from the construction process point of hull structure, especially some research of the structure connection node optimization.The paper study the hull structure from two aspects that guaranteeing structure strength and improving the construction technology of optimization,several aspects of the research as follow:(1) The optimization of luxury yacht hull typical structure research. We choose the typical structure of the luxury yacht as the research, on the premise of the new project we verify its original structure strength whether meet the requirements, otherwise, its original structure need design again in order to cooperate with other professional lofting of space and strength requirements.(2) On the strength of the hull sensitive areas respectively. Each major scheme base on the new ship modification and redesign, now some equipment need to be changed again, for example, the odd host power did not meet the requirements of power, now need to change the host as the position of the host and anti-rolling fin structure is in the same area, it is need to verify the strength of the structure in the region if meet the demand.(3) It’s sensitive to hull area verification on the rationality of structure optimization. As the reposition of the ship concept and the requirement of owner, some structure and the new scheme will result in some structure use to strengthened, the stiffener need to be modified or removed, in order to verify the strength of the modified need to do finite element simulation and the feasibility of the new scheme is calculated.(4) The research of the local structure optimization is based on the construction technology. Now the new layout and the structure of the original will have certain professional intervention, especially the professional lofting superstructure is very dense, requirements for the use of space is very high, so need to ensure the structural strength of the original structure form structure layout to optimize design is enough, at the same time the scheme of the structure optimization design need considering the construction work and the difficult of work.
