RESIN FLOW SIMULATION IN RTM PROCESS FOR THICK SECTION PARTS
-
摘要: 针对厚截面构件的RTM工艺过程,研究了三维树脂流动问题。基于六面体单元,采用有限单元/控制体积方法,开发了三维树脂流动过程模拟程序HEXCV。与解析解比较验证了HEXCV程序的稳定性和可靠性。算例研究表明,HEXCV程序可为工艺过程设计提供有效的参考依据。

Abstract: The resin flow in RTM process for thick section parts was investigated. A program HEXCV for three dimensional resin flow process was developed based on the hexahedral element with the finite element/control volume method (FE/CVM). The accuracy and the reliability of the HEXCV program were confirmed, compared with the analytical solutions. Numerical examples show that the HEXCV program can provide an effective reference for the process design. -
