摘　　要：免充气轮胎的聚氨酯支撑结构对轮胎诸多性能的发挥具有直接影响。以Tweel轮胎为例,在Abaqus中建立了轮胎的有限元模型,通过DOE设计分析了不同聚氨酯支撑结构参数对轮胎接地力学特性的影响规律;同时,为提升Tweel轮胎的抓地和减振性能,利用多目标优化理论完成了对聚氨酯支撑结构的优化改型设计。结果表明,聚氨酯支撑结构的宽度、厚度和圆弧曲率分别对轮胎的接地压力分布和接地面积具有不同程度的影响;通过对Tweel轮胎聚氨酯支撑结构的宽度、厚度和圆弧曲率进行优化设计后,有效增大了胎面接地面积的同时降低了其接地径向力,实现协同提升免充气轮胎抓地和减振性能的目标。相关研究成果对于我国免充气轮胎的研发和应用具有一定参考价值。The polyurethane support structure of non pneumatic tire has a direct impact on the performance of tire.Taking the Tweel tire as an example,the finite element model of tire is established in Abaqus,and the influence mechanism between different polyurethane support structure parameters and tire grounding mechanical characteristics is analyzed through DOE design.At the same time,in order to improve the grip and damping performance of the Tweel tire,the optimization and modification design of polyurethane support structure is completed by using multi-objective optimization theory.The results show that the number,width,thickness and arc curvature of polyurethane support structure have different effects on the grounding pressure distribution and grounding area of tire.The optimizing of the width,thickness and arc curvature of the polyurethane support structure of the Tweel tire,effectively improves the grip and reduces the grounding radial excitation force,and jointly improves the grip and vibration damping performance of the Tweel tire.The relevant research results have a certain reference value for the R&D and application of non pneumatic tires in China.
