| 摘 要： | 模具在使用过程中的变形会影响到复合材料制件的固化变形，为了控制复合材料制件的成型质量，就要了解框架式模具在热压罐固化成型工艺过程中的变形情况。建立了模具变形的数值模拟预报方法，将计算结果与实际模具测量结果进行对比，本文中所提供的有限元分析计算模型可对实际情况进行较为精确的模拟。考察了平板型框架式模具在整个固化工艺过程中的变形情况，数值计算结果表明：型面翘曲变形量与模具温度的分布有关，而与模具温度的大小无关；模具翘曲变形量的峰值出现在降温阶段的中间时刻，且该变形量能够保持一段时间；最大变形时刻整个模具型面与进入热压罐前相比中心位置的变形最大，周边位置的变形最小。

| Abstract: | For understanding the influence of deformations of the mould on process-induced deformations of the composite component,the geometrical deformation of framed-mould in autoclave processing was studied.A finite element model was developed to simulate deformations of the mould.And then an experiment was presented to demonstrate the use of the present finite element procedure.Deformations of a plate framed-mould in autoclave processing were studied.The results of numerical simulation show that deformations of t... |
