装配型架的设计对飞机产品的制造与装配具有重要意义.基于参数化的型架有限元分析法能很好地克服现有装配型架设计方法工作效率低下的弱点.基于飞机装配型架设计的基本原理,在模型简化原则的基础上,将参数化设计与有限元相结合,通过改变型架参数自动生成分析模型,并完成型架有限元分析,从而实现型架骨架的界面优化.该方法在一定程度上提高了型架分析的效率,可缩短实际生产工作周期,避免了大量人力物力的浪费.

The assembly fixture design is important to manufacture and assemble the aircrafts.The parametric finite element analysis method is proposed to avoid the low-efficiency of present design method.Based on the principle of assembly fixture design of the aircrafts and the rules of model simplification,parametric design and finite element analysis is combined,and the analysis model can be generated automatically by changing the parameters of fixtures.Through finite element analysis of the fixtures,the goal of frame section optimization can be achieved.This method has the advantages of promoting the efficiency of fixture analysis,shortening the production cycles,and avoiding the waste of human resources and materials.
