摘要/Abstract

摘要： 基于流体体积函数方法建立了高压绝缘拉杆真空辅助树脂浸润纤维过程的树脂空气两相流模型,其中包含模腔壁与纤维预制体之间缝隙区域和混编纤维预制体内的两相流模型;构建了绝缘拉杆几何模型并进行网格划分,采用有限体积法并通过Fluent软件完成了树脂空气两相流模型的求解;对绝缘拉杆模腔内全区域的两相流动及干斑缺陷进行仿真研究,通过实验验证了仿真研究的正确性,分析了缺陷产生的原因,给出了解决干斑问题的思路和方法,并通过仿真和实验验证了部分方法的可行性和有效性。

Abstract: Based on Volume of Fluid method, two-phase flow model of resin and air was established to describe vacuum assisted resin-impregnated fiber process for high voltage insulated pull rod. In the model, two kinds of two-phase flow sub-models were integrated, which separately describe the two-phase flow in the gaps between mould inner surfaces and fibre preform and the two-phase flow in mixed fibre preform. The geometric model of insulated pull pod was also established and then mesh generation was accomplished. By Finite Volume Method and using Fluent software, the two-phase flow model of resin and air was solved. In the whole mould area, the two-phase flow and dry spots formation were simulated. The correctness of simulation research was verified by experiments and the causes of dry spots were analyzed. Furthermore, thoughts and methods to eliminate dry spot defects were presented. Feasibility and effectiveness of some methods were verified by simulations and experiments.

Key words: volume of fluid method, dry spot, numerical simulation, defect analysis
