摘要

在总结复合材料 T 型加筋壁板制造经验的基础上，针对 Z 型长桁壁板这一特殊零件的制造工艺，重点研究了 Z 型长桁的树脂流动和厚度控制、静不稳定态的 Z 型长桁轴线度和姿态控制、长桁圆角处压力均匀传导，壁板组件固化变形分析以及蒙皮自动铺带轨迹规划等问题。通过在圆角处引入未硫化橡胶垫错台式分布模式，确保长桁圆角处压力均匀传递；利用 Z 型长桁半封闭内腔金属芯模合理布局，实现对长桁固化过程的姿态稳定调控；利用有限元仿真模型，结合软件二次开发功能，完成对加筋壁板固化变形的高效分析。最终实现 Z 型加筋壁板整体结构成型与内、外部质量的协同控制，为同类型产品的研制提供经验借鉴。

Abstract

Based on the experience of T-type composite stiffened panels

technical issues

such as the fabrication of Z-type stringers

the control of thickness and spring-back on Z-type stringers

the curing deformation predictions of the panel

the control of stringer axis and the trajectory planning of ATL

were mainly researched. By introducing the staggered distribution mode of unvulcanized rubber pad at the fillet

the uniform transmission of pressure of the stringer was ensured. The rational layout of the metal core mold in the semi closed cavity of the Z-typed stringer was used to realize the stable attitude control during curing process. Using the finite element simulation model and the secondary development function of the simulation model

the efficient analysis of the curing deformation of the stiffened panel was achieved. Finally

the overall structure molding and the collaborative control of internal and external quality for Z-type stiffened panel are realized

which provides experience for the development of similar products.
