摘要: 针对民机复合材料C形梁结构的固化变形问题,建立了包括传热分析模型、固化动力学分析模型、弹性模量模型、树脂收缩模型在内的仿真预测模型,对C形梁缩比件结构的固化变形进行了预测,预测结果与试验结果相比,具有较小的误差。本文将固化变形的仿真预测结果用于指导C形梁缩比件的模具型面修正调节,用型面调节后的模具制备C形梁的变形测量结果满足结构精度要求,实现了对C形梁结构固化变形的有效控制。

Abstract: Aiming at the curing deformation of the C-shaped beam structure of the civilian composite material, the simulation prediction models including heat transfer analysis model, curing kinetics analysis model, elastic modulus model, resin shrinkage model are established, and the C-shaped beam shrinkable. The curing deformation of the structure is predicted, and the prediction results have a small error compared to the test results. In this paper, the simulation prediction result of the curing deformation is used to guide the mold type correction adjustment of the C-shaped beam scaled-down component. The modification measurement of the C-shaped beam prepared by the mold adjustment is satisfied with the structural precision requirements, and the effective control of curing deformation of C-shaped beam structure is realized.
