This research aimed to develop a dynamic finite element (FE) model of non-pneumatic tire (NPT) to study the mechanical behaviors of rolling NPT. The generalized Maxwell’s viscoelastic material was combined with linear elastic material model. This material model was fitted with results of tensile and compressive testing on actual NPT specimen. The FE model of rolling NPT on curvature and flat surface under supporting load of 14 kN and speed of 11 km/hr were carried out to compare with the actual experiment of rolling NPT on drum testing machine. The high-speed video camera was used to capture NPT’s spoke deformation at various angular position corresponding to time. The comparison results shown good agreement between the actual experiment and both FE models, which yielded average error of 3.68 and 3.89% for FE model of rolling NPT on drum and flat surface, respectively. The maximum dynamic values of impact force, displacement, and stress were higher than static values of 1.06, 1.16 and 1.805 times, respectively. Finally, the limitation of rolling NPT’s performance on flat plate was analyzed. The shear stress between shear band and spoke under maximum load of 20 kN and velocity of 15 km/hr was found at 1.7277 MPa.

本研究旨在开发非充气轮胎 (NPT) 的动态有限元 (FE) 模型，以研究滚动 NPT 的力学行为。广义麦克斯韦粘弹性材料与线弹性材料模型相结合。该材料模型与实际 NPT 试样的拉伸和压缩测试结果相吻合。在14 kN的支撑载荷和11 km / hr的速度下，在曲率和平面上滚动NPT的有限元模型与在滚筒试验机上滚动NPT的实际实验进行了比较。高速摄像机用于捕捉NPT在不同角度位置对应时间的辐条变形。比较结果表明，实际实验与两种有限元模型之间具有良好的一致性，平均误差分别为 3.68 和 3。在滚筒和平面上滚动 NPT 的 FE 模型分别为 89%。冲击力、位移和应力的最大动态值分别高于静态值的 1.06、1.16 和 1.805 倍。最后，分析了轧制NPT在平板上的性能限制。在最大载荷 20 kN 和速度 15 km/hr 下，剪切带和辐条之间的剪切应力为 1.7277 MPa。
