摘　　要：采用Ansys有限元分析平台构建全船模型,通过插值和网格划分2种方法划分模型网格,并在不同载荷情况下,通过3种力学方程模拟和校核船舶模型的抗损程度以及承载强度,分析船舶结构性能,完成船舶模型结构尺寸优化。结果显示:该方法能够获取不同载荷下船舶不同结构部位的应力分布结果,不同载荷下,船舶首部舱段结构和甲板支撑结构发生显著的应力集中现象,最大发生接近8 cm的变形;对船舶结构尺寸优化后,结构的最大应力不超过应力的上限值400 MPa,整体船舶质量也逐渐发生轻量化。Using Ansys finite element analysis platform to build the whole ship model,through the two methods of interpolation and mesh partition model grid,and in different load cases,through three mechanics equation simulation and checking resistance loss of the model of a ship and bearing strength,performance analysis of ship structure,and USES the Ansys finite element analysis platform to complete the model structure size optimization of the ship.The results show that the method can obtain the stress distribution results of different structural parts of the ship under different loads.Under different loads,the bow cabin structure and deck support structure have significant stress concentration phenomenon,and the maximum deformation is close to 8 cm.After optimizing the size of the ship structure,the maximum stress of the structure does not exceed the upper limit of stress 400 MPa,and the overall ship mass is gradually lightened.
