【摘要】 纤维增强材料(FRP)是一种具有比强度高、比刚度高、低密度、耐腐蚀性等优越性能的复合材料。纤维缠绕是制造高强度复合材料制品的一种重要工艺方法,广泛应用于航空、航天、建材、化工等领域。在纤维缠绕工艺中,连续纤维被缠绕到芯模上以形成复合材料制品。 纤维缠绕制品通过缠绕线型的三种基本类型生产出来,它们是平面缠绕、螺旋缠绕和环向缠绕。纤维缠绕工艺适合于制造旋转对称制品。在缠绕制品中,纤维缠绕复合材料压力容器因其低成本、重量轻和安全性好,在军用和民用中被广泛应用于储存气体或流体。 本文在纤维缠绕基本规律的基础上建立了一般曲面上纤维缠绕的数学及几何模型导出了纤维稳定的条件,研究了环形容器的缠绕线型设计方法,对环形容器芯模的运动规律、绕丝嘴的运动规律及缠绕线型进行了分析。 在Visual C++环境下,结合OpenGL图形处理软件对环形芯模进行三维建模并用OpenGL中的操作命令实现环形容器纤维缠绕的动态仿真。OpenGL是一个被广泛应用于虚拟现实、动画、CAD/CAM/CAE等领域的性能优越的三维图形应用程序库,目前已成为三维图形开发的标准。本文将环形容器的芯模主要几何尺寸进行参数化,利用OpenGL的相关命令和函数对芯模进行三维建模:然后通过编辑仿真程序而进行纤维缠绕的仿真。 充分利用VisualC++的MFC(Microsoft基本类库)资源编辑程序,调用OpenGL的三维图形程序库,实现逼真的模拟纤维缠绕环形容器的生产过程,减少工程设计人员的计算强度,降低生产成本,提高生产效率。更多还原

【Abstract】 Fiber Reinforce Plastic (FRP) is a kind of composite materials which has high specific intensity, high specific rigidity, low density, excellent corrosion-resistance. Filament winding (FW) is an important method of manufacturing high-intension composite material products, and it is extensively applied in the aviation, astronautic, chemical industry and building material etc. It is the process in which continuous fibers are would on a mandrel to form a composite component.Filament-wound products are produced by using one of the three types of winding patterns: polar, helical and hoop. Filament winding process is well suited to the manufacture of rotationally-symmetric components. Filament-wound composite pressure vessles are widely used for containment of gases/fluid in both military and commercial applications because of their low cost, wight savings and safty.We atudied the method of toroidal vessel after FW pattern has been analyzed, and the feed-eye movement is also analyzed.In the environment of Visual C++, dynamic simulation of FW can be realized by using OpenGL. OpenGL is a high qualified libtaty of 3Dgragh application,and now it has become the development standard of 3D graghics . In this paper, the simulation model has been definded by reometric parameters of totoidal vessel,which has been sreuctured by using relational commands and functions of OpenGL;then FW has been simulated.MFC resource can simplified the programming, then vividly simulate the process of filament winding with OpenGL. It can reduce the production cost and increase the productivity.更多还原
