剪切加热已被纳入一个粘弹性模型的牵引通过一个简单的迭代方法。计算出的牵引力现在随着实验观察到的滑动的增加而呈现最大值。计算和测量结果（无自旋）吻合良好，除了在非常低的滑移和在两个温度较高。有迹象表明，这是可以纠正的，更现实的润滑剂剪切模量值可以使用，如果辊顺应性包括在模型中。牵引滑移曲线拟合所需的压力粘度系数和导热系数的值与独立测量值合理一致;牛顿极限应力被假定为与压力无关，并与绝对温度成比例，符合速率理论。在存在旋转的情况下，计算的牵引力比测量的大15%。随着负载、速度和温度的变化，计算出的趋势大致正确。该模型应是有用的，在其目前的形式为初步的…
Shear heating has been incorporated into a viscoelastic model of traction by a simple iterative method. The computed traction now exhibits a maximum with increasing slip as observed experimentally. Computed and measured results (without spin) agree well, except at very low slip and at the higher of two temperatures. There are indications that this could be corrected and that more realistic values of lubricant shear modulus could be used if roller compliance was included in the model. Values of pressure viscosity coefficient and of thermal conductivity required for fit of traction-slip curves are in reasonable agreement with independent measurements; Newtonian limit stress is assumed to be independent of pressure and proportional to absolute temperature in accordance with rate theory. With spin present, the computed traction is up to 15 percent larger than measured. Computed trends with changing load, speed and temperature are approximately correct. The model should be useful in its present form for prelim...
