This paper presents a simple code written in MATLAB for simulating and optimizing the draping of a composite material fabric onto a mold. Being simple and kinematically based, the algorithm can be used to predict the final fiber orientations after a fabric has adapted to a double-curved mold surface. These fiber orientations will in turn govern the mechanical properties of the composite part and a draping analysis is thus advantageous in connection with a structural analysis as well as manufacturing. The code is intended for educational purposes and can be found in the Appendix of the paper and on the repository at https://doi.org/10.5281/zenodo.4316860 along with a Python implementation. After a description of the code, various extensions are introduced, including a framework for optimization of the draping parameters.

本文介绍了一个用 MATLAB 编写的简单代码，用于模拟和优化复合材料织物在模具上的悬垂。该算法简单且基于运动学，可用于预测织物适应双曲面模具表面后的最终纤维取向。这些纤维取向将反过来控制复合材料部件的机械性能，因此悬垂分析在结构分析和制造方面是有利的。该代码用于教育目的，可以在论文的附录和存储库中找到，网址为 https://doi.org/10.5281/zenodo.4316860 以及 Python 实现。在代码描述之后，引入了各种扩展，包括用于优化悬垂参数的框架。
