橡皮囊成形是飞机钣金件的一种重要成形工艺方法。有限元数值模拟技术越来越多地被用于分析板料成形过程中可能存在的问题。本文针对目前大多数有限元软件没有针对橡皮囊成形模块的现状,基于橡皮囊成形工艺,应用PAM-STAMP 2G软件提供的开发宏模板的功能,以一个典型的钛合金钣金零件为例,研究钛合金钣金零件橡皮囊成形仿真技术,为飞机钛合金钣金零件的橡皮囊成形设计和生产提供依据。
Rubber bladder forming sheet metal aircraft is an important forming process. Finite element numerical simulation techniques are increasingly used to analyze possible problems in sheet metal forming. In view of the fact that most of the finite element software does not address the current situation of the rubber capsule forming module and the function of developing the macro template provided by the PAM-STAMP 2G software is based on the rubber bladder forming technology, taking a typical titanium alloy sheet metal part as an example, Titanium alloy sheet metal parts rubber capsule forming simulation technology for aircraft titanium alloy sheet metal parts forming the rubber capsule design and production provide the basis.
