The heat generation curves of seven rubber materials used in tires with the changes of temperature have been obtained by using Dynamic Mechanics Analysis technique on NETZSCH DMA242 instrument, knowing that the heat generation of every other rubber materials except inner liner rubber changes lightly alone with the temperature within 10℃~80℃. According to the Fourier law, the heat transfer coefficients of tire rubber are measured by stable method on self-made experiment instrument. The coefficients changes lineally within 20℃~80℃ and the relation formulas λ=λ〓+bt are given out attached with λ〓 and b. The specific heat of tire rubber are measured on Differential Scanning Calorimeter NETZSCH DSC204 and the relations with temperature are linear and the formula is c=c〓+bT, where c〓 and b gained from experiment result data are presented in the paper. The heat convection coefficients on the surface of rolling tire are measured according to the principle of heat-mass transfer analogy principle after simplifying rolling tire into rotating disk with straight movement on wind channel. The relation with rotation speed of disk is linear as h=5. 399+0.0258n and the relation with straight line speed of tire is linear too, h=
论文采用动态力学分析技术,使用NETZSCH DMA 242型实验仪,获得了轮胎用七种胶料的生热率随温度变化曲线,确知除内衬层胶以外,其它各种胶料在一般胎温范围内(10℃~80℃)的生热率随温度变化不大;轮胎胶料的导热系数根据傅立叶定律的基本原理,采用稳态法在自行搭建的实验台上进行测试,结果表明,材料的导热系数在20℃~80℃的温度范围内随温度呈线性变化,论文给出了各种材料导热系数的线性变化的关系式λ=λ〓+bt及其λ〓和b的值;轮胎胶料的比热运用差式扫描量热原理,在NETZSCH DSC204型DSC实验仪上进行测试,结果表明,胶料的比热随温度的变化呈线性变化,其关系可用c=c〓+bT表示,文中给出了根据实验数据拟合的c〓、b的值;对轮胎表面的对流换热系数的测定,本文先将滚动的轮胎简化为有直线运动的旋转圆盘,而后采用萘升华热质比拟技术,在风洞中测量了滚动轮胎表面的对流换热系数,结果表明,圆盘表面对流换热系数与转速呈线性关系,即h=5.399+0.0258n,轮胎表面对流换热系数与其直线运动的速度呈线性关系,即h=
