【摘要】 采用稳态法测量 2 0 5 /75R15轮胎各部位橡胶材料的导热系数。试验结果表明 ,轮胎不同部位橡胶材料的导热系数随温度变化而改变 ,在本试验所研究的 2 0～ 80℃温度范围内 ,二者呈线性关系。另外 ,在相同温度下不同橡胶材料的导热系数不同。更多还原

【Abstract】 The thermal conductivities of the rubber compounds in various parts of 205/75R15 tire were measured by steady state method.The results showed that the thermal conductivities of the rubber compounds in various tire parts were functions of temperature,and linear with the latter in the range of 20～80 ℃ used in this study;and the conductivities of different rubber compounds were different at the same temperature.更多还原
