The objective of the program is to analyze the problem of thermal elastohydrodynamic lubrication of rolling/sliding contacts and to develop an expert system model to aid in the design process of tribo- systems. The theoretical model will analyze each component of heat generation and dissipation within the lubricant film and the rolling/sliding elements. Hence, the lubricant operating temperature for prescribed boundary conditions is determined. The pressure and temperature distributions developed in tribo-systems induce mechanical and thermal stresses in the rolling/sliding elements. These stresses could generate and propagate fatigue cracks in the machine elements. The theoretical model will be used to predict the pressure distribution, the temperature distribution, and the mechanical and thermal stresses generated due to the pressure and temperature for different geometries, velocities, loads, and lubricants.

该计划的目标是分析滚动/滑动接触的热弹性流体动力润滑问题，并开发一个专家系统模型，以帮助设计摩擦系统。该理论模型将分析润滑油膜和滚动/滑动元件内产生和消散热量的每个组成部分。从而确定了润滑油在规定边界条件下的工作温度。在摩擦系统中形成的压力和温度分布在滚动/滑动元件中引起机械和热应力。这些应力会在机械元件中产生和传播疲劳裂纹。该理论模型将用于预测压力分布、温度分布以及不同几何形状、速度、负载和润滑剂的压力和温度所产生的机械和热应力。
