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.
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.
