摘　　要：介绍了有限元法优化技术在一种船舶设备的性能提高设计中的应用.首先通过有限元校核发现,某齿列结构传力件已达不到新生产能力下的强度要求,须在保持边界结构不变的前提下进行重新设计;然后使用有限元软件ANSYS中的拓扑优化功能优化了此传力件结构,在构件重量基本不变的约束条件下满足了强度要求.In this paper, applications of Finite Element Method to a marine assembly＇s upgrade are introduced. Firstly, through the finite element anal）sis of the strength, it is found that one load arm couldnt match up to the strength standard in the new grade, which need redesign without modification of its boundary. Then this load arm is optimized with the topological function in ANSYS and the new design can meet the strength standard with minute increase in mass.
