有限元分析在PDA大型游艇吊具设计中的应用

Application of finite element analysis in design of PDA lifting attachment for large-scale barge

介绍Ansys有限元分析技术在受限吊装工程实例中的应用,通过Ansys有限元分析得到PDA吊具的应力、位移和失稳云图及曲线,为优化吊具结构及论证不用可调拉杆的零分力吊装的可行性提供了依据。

The paper introduces the application of Ansys finite element analysis technology in the limited hoisting pro- ject. Through Ansys finite element analysis, the stress, displacement, instability nephograms and curves of the PDA lifting attachment are figured out, which provides reference for optimization of lifting attachment structure and demonstrating the feasibility of zero component force hoisting without adjustable pull rod.
