摘　　要：利用有限元软件MSC.Patran的二次开发工具PCL(Patran Command Language),结合Matlab和VC#语言,开发了金属隔膜贮箱设计与分析系统.推导得到金属隔膜关键构型参数间的几何关系,实现了隔膜的设计与仿真分析的自动进行.系统的主要功能包括参数化有限元模型的建立、材料属性及边界条件自动施加、翻转过程的数值仿真以及丰富的后处理功能.系统中集成了隔膜设计与翻转仿真领域的工程经验,避免重复工作,提高工作效率,降低研发成本,在金属隔膜贮箱的结构设计和分析领域有较高的实用意义.The diaphragm structure design and analysis system used in the metal diaphragm tank is developed by using the secondary development language tool PCL（Patran Command Language）provided in MSC.Patran,and applying Matlab and VC# programming software to achieve the specific functions.The correlation between key structure parameters of the metal diaphragm is derived,so that the system can perform the design and simulation work automatically.Main functions of the system include establishing the parametric finite element model,adding material property and boundary conditions,simulating the entire process of the expulsion behavior and abundant post-processing functions.The professional knowledge and experience are integrated in the system to avoid the unnecessary repetitive work.The system can evidently improve work efficiency and reduce the research cost,which shows the high practicability significance in the metal diaphragm of propulsion tank design and analysis area.
