9409528 Chang A study of the mixed lubrication regime which lies between the micro-elastohydrodynamic and boundary lubrication regimes will be conducted. The modeling will be based on using the full surface roughness for the asperity interaction determinations and a roughness with the short wavelength components filtered out for the calculations of the hydrodynamic pressure distribution. Thermal effects and three-dimensional roughness effects will be included in tests of the algorithm's robustness. The model will be validated in tests with tribological surfaces coated with ceramic coatings or with solid lubricants. ***

9409528 Chang将进行介于微弹性流体动力学和边界润滑状态之间的混合润滑状态的研究。 建模将基于使用完整的表面粗糙度来确定粗糙度相互作用，并使用过滤掉短波长分量的粗糙度来计算流体动压分布。 热效应和三维粗糙度效应将包括在算法的鲁棒性测试中。 该模型将在摩擦学表面涂有陶瓷涂层或固体润滑剂的测试进行验证。 ***
