摘　　要：非充气轮胎不存在爆胎风险,疲劳性能是其设计过程中重点关注的性能指标。本工作基于橡胶材料的疲劳裂纹扩展理论和临界平面分析法,运用Abaqus和Endurica软件联合仿真的有限元分析方法,进行了非充气轮胎弹性支撑体的疲劳寿命预测;系统分析了有限元网格类型及网格尺寸对非充气轮胎弹性支撑体的疲劳寿命的影响,从而为高性能、长寿命非充气轮胎的优化设计提供理论和技术支撑。The non-pneumatic tires do not have the risk of burst,and the fatigue performance is a key performance indicator during their design process.Based on the fatigue crack propagation theory of rubber materials and the critical plane analysis method,the fatigue life prediction of the elastic spoke of the nonpneumatic tire was carried out using the finite element analysis method of the joint simulation of Abaqus and Endurica software.The influence of finite element mesh type and mesh size on the fatigue life of the elastic spoke of the non-pneumatic tire was systematically analyzed,providing theoretical and technical supports for the optimization design of high-performance and long-life non-pneumatic tires.
