Abstract

Axial crush tests on Uniform Thickness (UT) and Functionally Graded Thickness (FGT) tubes have been performed for external inversion process, and crashworthiness performance, and benefits of FGT tubes compared with their UT equivalents. Furthermore, in order to find detail verification about crush process of FGT tubes, Finite element (FE) models developed using explicit FE code under axial loading. Then, these FE models validated by experimental tests to ensure that they can accurately predict the responses of FGT inversion tubes. Our study shows that tube thickness distribution, die radius, and coefficient of friction between die and tube have great influence on the responses of FGT tubes inversion. The results give new design ideas to improve crashworthiness performance of inversion tubes. DOI: https://doi.org/10.52783/pst.272

厚度分布可变的管材外反转挤压分析

对均匀厚度（UT）和功能分级厚度（FGT）钢管进行了轴向挤压试验，以了解外部反转过程、耐撞性以及 FGT 钢管与其等同的 UT 钢管相比的优势。此外，为了详细验证 FGT 管的挤压过程，使用明确的 FE 代码开发了轴向加载下的有限元 (FE) 模型。然后，通过实验测试对这些有限元模型进行验证，以确保它们能够准确预测 FGT 反转管的响应。我们的研究表明，管子厚度分布、模具半径以及模具与管子之间的摩擦系数对 FGT 反转管的响应有很大影响。研究结果为提高反转管的防撞性能提供了新的设计思路。DOI: https://doi.org/10.52783/pst.272
