飞机装配型架有限元分析的参数化技术研究

Research of Parameterized Technology for Finite Element Analysis of Aircraft Jig

基于CATIA平台,首先把型架骨架抽象为线框结构,并在此基础上提出层面分解驱动方法,实现对骨架线框的参数化驱动。对基于层面分解驱动方法的装配型架骨架有限元分析流程作了研究,提高了相似型架有限元分析的效率,并给出了应用实例。

Based on CATIA,it proposes the method of plane separation drive with the sketch structure which is abstracted from frame of aircraft jig.The method can generate the sketch structure.It researches the process of finite element analysis of aircraft jig based on the method of plane separation drive.The efficiency of analysis for similar aircraft jig can be greatly improved,and a practical example is given to illustrate the application.
