辐板式聚氨酯轮胎的侧偏滚动性能研究

建立聚氨酯辐板与橡胶胎面相复合的辐板式聚氨酯轮胎模型，并采用有限元软件Abaqus分析其在侧偏滚动状态下的力学性能、接地性能和操控性能。结果表明：相比子午线橡胶轮胎，辐板式聚氨酯轮胎胎面胶和带束层帘线的受力分布更均匀，可有效避免带束层脱层现象的发生；支撑板的上下两端及中部易发生疲劳损坏，因此合理地设计支撑板结构十分必要；侧偏刚度和回正刚度相差不大。

Study on Cornering Rolling Performance of Polyurethane Radial Tire

:A model of radial plate polyurethane tire which combined polyurethane wheel disk and rubber tread was established,and the mechanical performance,grounding performance and handling performance of the tire under cornering rolling condition were analyzed by Abaqus finite element software.The results showed that,compared with radial rubber tire,the force distribution of tread and belt cord of the polyurethane radial tire was more uniform,which could effectively prevent the separation of belt.It was found that the upper and lower ends and central part of the support plate were more likely to be damaged due to fatigue,which made the design of support plate structure very critical.In addition,the cornering stiffness and aligning stiffness were almost the same.
