摘　　要：基于超弹性本构方程和热力耦合的有限元模拟方法,对实心轮胎的稳态温度场和滚动阻力进行了预测。首先,建立实心轮胎静态加载三维模型,得到接地压力分布和静刚度曲线;其次,对轮胎施加稳态滚动速度,提取轮胎滚动一周的应力、应变数据,并进行傅里叶级数高精度拟合,用MATLAB软件计算出迟滞能量损耗和生热率;最后,将生热率导入轮胎的生热模型得到轮胎稳态温度场,进一步计算出轮胎稳态滚动时的滚动阻力,并预测稳态滚动速度和垂直载荷对滚动阻力的影响。Based on hyperelastic constitutive equation and thermal-mechanical coupling finite element method,the steady state temperature field and rolling resistance of solid tire were predicted in this study.Firstly,a three-dimensional static loading model of solid tire was established,and the contact pressure distribution and static stiffness curve were obtained.Secondly,the rolling speed of the tire was applied to achieve the stress and strain data of the tire rolling a circle,which were fitted by Fourier series with high precision.The hysteresis energy loss and heat generation rate were calculated by MATLAB software.Finally,the heat generation rate was imported into the tire heat generation model to obtain the steady state temperature field,and then the rolling resistance during steady state rolling was calculated,and the influences of rolling speed and vertical load on the rolling resistance were predicted.
