摘要: 通用有限元分析软件ANSYS分析了材料拉伸弹性模量和槽体壁厚对复合材料槽型壳体拉伸变形的影响。结果表明,提高拉伸弹性模量和增加槽体壁厚有助于减小槽体变形。但是,材料的拉伸弹性模量、槽体的厚度与槽体变形三者之间并不呈线性递减关系。通过理论计算,确定出最合适的槽体厚度和拉伸弹性模量值,这样既能有效控制槽体的变形,还能起到节约成本和优化工艺的作用。

Abstract: To estimate the influence of tensile modulus and thickness of composite cell on the tensile deformation, the commercial finite element ANSYS software was applied to this study. The results show that it will help to decrease the tensile deformation by increasing the tensile modulus and thickness of cell. However, the deformation is nonlinear with the tensile modulus and the thickness. The most appropriate value of the tensile modulus and thickness were determined based on the calculations of ANSYS, and it will not only effectively control the tensile deformation of the cell, but also can low cost and simplify the process engineering.
