摘要
对于大尺寸复合材料零件成型所用的大型框架式模具,在设计过程中需要使模型建模及更改快速化,需要详细分析模具在实际使用工况下的应力及变形、模具在固化过程中的温度分布及变形情况,并在设计过程中考虑尺寸补偿及回弹补偿,以使模具设计达到高效、精准、优化的目的;使模具结构更好地满足复材零件成型精度要求。
For the large-scale frame-mould molding of big size composite parts, there are several factors should be considered during mould design： modeling and changing the mould model quickly, analysis of stress and deformation of the mould at actual using conditions, analysis of temperature and deformation of the mould during curing process, consideration of size compensation and spring back compensation. These processes can make the mould design more efficiently, more accurately and more superior, then the mould structure can meet the precision requirement of composite parts better.
