Abstract

A non-pneumatic tire (NPT) overcomes the shortcomings of a traditional pneumatic tire such as wear, punctures and blowouts. In this respect, it shows great potential in improving driving safety, and has received great attention in recent years. In this paper, a carbon fiber-reinforced polyethylene terephthalate (PET/CF) honeycomb is proposed as a support structure for NPTs, which can be easily prepared using 3D printing technology. The experimental results showed that the PET/CF has high strength and modulus and provides excellent mechanical properties. Then, a finite element (FE) model was established to predict the compression performance of auxetic honeycombs. Good agreement was achieved between the experimental data and FE analysis. The influence of the cell parameters on the compressive performance of the support structure were further analyzed. Both the wall thickness and the vertically inclined angle could modulate the mechanical performance of the NPT. Finally, the application of vertical force is used to analyze the static load of the structure. The PET/CF honeycomb as the support structure of the NPT showed outstanding bearing capacity and stiffness in contrast with elastomer counterparts. Consequently, this study broadens the material selection for NPTs and proposes a strategy for manufacturing a prototype, which provides a reference for the design and development of non-pneumatic tires.

摘要

非充气轮胎（NPT）克服了传统充气轮胎诸如磨损、扎破和爆胎等缺点。在这方面，它在提高驾驶安全性方面显示出巨大潜力，并且近年来受到了极大关注。本文提出了一种碳纤维增强聚对苯二甲酸乙二酯（PET/CF）蜂窝作为非充气轮胎的支撑结构，其可以使用3D打印技术轻松制备。实验结果表明，PET/CF具有高强度和模量，并提供优异的力学性能。然后，建立了有限元（FE）模型来预测负泊松比蜂窝的压缩性能。实验数据与有限元分析之间取得了良好的一致性。进一步分析了胞元参数对支撑结构压缩性能的影响。壁厚和垂直倾斜角均可调节非充气轮胎的力学性能。最后，通过施加垂直力来分析结构的静载荷。与弹性体对应物相比，作为非充气轮胎支撑结构的PET/CF蜂窝表现出出色的承载能力和刚度。因此，本研究拓宽了非充气轮胎的材料选择范围，并提出了制造原型的策略，为非充气轮胎的设计和开发提供了参考。
