摘　　要：根据轮胎力学场的数值分析结果,采用傅里叶级数拟合单元在轮胎滚动一周内的应力应变变化,利用傅里叶级数系数计算轮胎单元损耗应变能与生热率。通过正交验法设计台架试验,测试了不同速度、载荷、胎压和环境温度下轮胎不同部位的温度,以验证数值分析结果。对应台架试验方案各工况,模拟了斜交胎在不同工况下的稳态温度场分布,数值计算结果与试验值基本一致。在此基础上讨论了环境温度、速度、载荷、胎压等因素对轮胎温度的影响,并给出了胎肩最高温度与各因素之间的关系公式。Fourier series was utilized to fit the stress and strain of tire in a roiling cycle by means of mechanic-field analytic result. Element dissipation energy and heat generation rate were calculated according to the obtained Fourier coefficient. The orthogonal experimental method was used to design the roadwheel test scheme. The temperature at the different locations was measured at the case of the different velocity, loads, inflated pressures and air temperatures and the referenced basis was offered to verify the validity of numerical analytic result. Steady temperature field was simulated at the different cases corresponding to each case of roadwheel experiments and the results were basically consistent with the experimental data. The influences of environmental temperature, velocity, load, inflated pressure on the tire temperature distribution was discussed. The equation of relationship between the maxim temperature of tire shoulder and all influences factors was offered.
