摘要：

针对某型号航空结构零件，基于ABAQUS/Explicit有限元仿真平台，建立了半固化GLARE层板橡皮垫成形的有限元模型，研究了橡皮垫成形过程中不同材料的应力、应变分布以及变形规律，分析了利用该种成形工艺实现GLARE层板成形的可行性及具体工艺过程，最后通过实验验证了模型的可靠性。研究结果表明：半固化GLARE层板适用于橡皮垫成形工艺，能够得到质量较好的零件。通过对半固化成形后的零件进行真空固化处理，能够有效避免零件的翘曲变形等不利因素，最终制造出满足生产要求的合格零件。

For the structured part in a certain type of aircraft, and the finite element model of semi-cured GLARE laminates in the rubber pad forming process was established by finite element modeling platform ABAQUS/Explicit, and the stress-stain distributions and deformation laws of different materials were investigated during the rubber pad forming procedure, and the feasibility of GLARE formed by this technology as well as its specific process were analyzed to verify the model reliability by experiments. The results indicate that a good quality part made of GLARE laminates by rubber pad forming process can be obtained. The semi-cured part is processed by the vacuum curing to avoid the adverse factor like warpage effectively,and a qualified part that meets the production requirement is produced finally.
