子午线轮胎接地特性与胎冠温度场关系的研究

以385/55R22.5载重子午线轮胎为研究对象，采用有限元分析方法研究轮胎内轮廓、仿生胎面弧和带束层结构等对接地特性和胎冠温度场的影响。结果表明：内轮廓与仿生胎面弧设计对胎冠温度影响显著；4层带束层结构的胎冠温度低于“3＋0°”带束层结构；平均接地压力、接地面积、硬度因数、接地宽度、接地压力偏度值和印痕面积参数与胎冠温度具有较强的相关性。;In this study，using 385/55R2.5 truck and bus radial tire as an example，the influence of inner contour，bionic tread arc and belt structure of tire on the grounding characteristics and crown temperature distribution was investigated by finite element analysis.The results showed that，inner contour and bionic tread arc significantly affected tire crown temperature，and the crown temperature of the tire with 4-layer belt structure was lower than that with “3＋0°” belt structure.It was found that the average ground contact pressure，ground contact area，hardness coefficient，ground contact width，ground pressure deviation and footprint area of tire were strongly associated with tire crown temperature
