摘　　要：针对固化残余应力和变形预测问题,建立了残余应力和固化应变的广义麦克斯韦黏弹性本构模型。基于ANSYS APDL技术对线包固化工艺中残余应力和变形进行了数值模拟,研究了固化过程中线包残余应变应力的变化规律及分布,分析了工艺参数对应力应变的影响。结果表明:靠近线轴的初始缠绕层应变较大,沿轴向呈现出由中间向两端逐渐变大的应变分布特征,线包内部存在明显不均匀的残余应力;残余应力和应变随固化温度和缠绕层数的增大而增大,线包的最大变形量却随着线包厚度的增大而变小。There are great effect for storage transport and payingoff stability of fiber optic cable package that residual stress and deformation.According the residual stress and the deformation trend,a generalized Maxwell constitutive model is established on residual stress and curing strain.Based on ANSYS APDL,numerical simulation has been conducted for residual stress and deformation of fiber optic cable package curing process.The chang rule and diagram of residual stress-strain has been researched,the effect of technological parameter were analyzed according stress-strain.The results show that relatively larger strain present to bottom area nearby bobbin,the strain becomes larger gradually from the middle to both ends along the axial direction,and there are uneven residual stress within fiber optic cable package.Residual stress-strain becomes larger along with the growth of curing temperature and the layer number of twisting,the max deformation of fiber optic cable package becomes smaller along with the growth of the layer number of twisting.
