Research on Automatic Modeling Method of Composite Conical Shell

复合材料具有高减重效率及比强度、比刚度高的优点,已经广泛地应用于航空结构件。为了计算层合板复合材料的层间应力,必须按层建立三维有限元模型。应用有限元软件进行锥壳复材的模型建立,通过PCL编程实现材料特性的自动建立方法。为层压复合材料板层间应力的计算提供一种快捷、准确、有效的模型建立途径。

Composite materials have the advantages of high weight reduction efficiency, high specific strength and specific stiffness, and have been widely used in aviation structures. In order to calculate the interlaminar stress of composite laminates, a three-dimensional finite element model must be established. The finite element software is used to establish the model of the composite material of conical shell, and the automatic establishment method of material characteristics is realized by PCL programming. It provides a fast, accurate and effective way to establish the model for calculating the interlaminar stress of laminated composite plates.
