基于复合材料缠绕成型过程对工艺参数的要求，针对缠绕过程中芯模变形和加热温度对缠绕层应力分布影响等问题，建立温度和芯模变形作用下的缠绕张力设计数学模型。研究了温度引起缠绕层的应力分布解析模型，分析了缠绕内层和芯模在外层压力影响下制品的应力分布，结合3种典型的张力缠绕模型，研究了芯模内外径比以及张力锥度系数对缠绕层剩余张力的影响。提出实现缠绕制品等剩余张力下，初始缠绕张力和温度的理论关系。计算解析解与现有文献一致，文章考虑芯模变形和温度对制品应力影响，计算方法更符合实际，研究结果可用于缠绕张力设计和固化应力分析。

Based on the requirements of the process parameters in composite filament winding, aiming at the effect of mandrel deformation and heating temperature on the distribution of winding layers in winding process,the mathematical model of winding ten?sion was established.The analytical model of temperature?induced stress distribution in winding layers as well as the stress distribu?tion of inner layers and mandrel under the outer pressure was investigated.Based on three typical tension winding models,the influ?ence of the mandrel diameter ratio and taper tension coefficient on remaining tension was researched and the theoretical relationship of initial winding tension and temperature was proposed to achieve the equal remaining tension.The analytical solution was based on existing literature;while the deformation of mandrel and influence of temperature was taken into account.The results can be used for the stress analysis of curing and the design of winding tension.
