摘　　要：MSC/NASTRAN是我国造船行业公认的有限元软件,它的前后处理器为建立船体三维有限元模型提供了强大的手段,但由于船体结构的复杂性,仍使得船体有限元分析成为非常繁重的工作,故实现参数化建模已成为船体结构分析人员越来越关注的问题。本文以实际工程项目“强梁腹板特殊开孔应力分析及补强方法的研究”为背景,介绍了作者利用PCL语言实现参数化建立强梁特殊开孔的有限元模型的技术,并编制了相应的程序。应用该程序能大大缩短全部方案模型的建模时间,并提高了效率,体现了PCL语言在实现参数化建模方面的优越性。In ship building, SMC/NASTRAN as a common FEM program in the world is selected for ship structure analysis as a standard program. The pre&post processor of MSC/PATRAN provides a very effective way to create 3D ship models. Howover, due to the complexity of ship structure, the finite element analysis for ship structure became a tedious job, so that the structure engineers are more and more interested in the parameterized-modeling technology for 3D FEM model of ship. In this paper, in the background of the project 'the Stress Concentration of the Special Holes on Webs and the Study for Their Strengthening Methods', the authors introduced the fundamentals and the methods to create element models parametrically with the use of PCL language of MSC/PATRAN. By using the program so derived, the work has become easily and effectively. It shows that the PCL language has some advantages on parametrically modeling.
