Design and Development of Expert System for Thermal Elasto- hydrodynamic Lubrication of Rolling/Sliding Contacts

该计划的目标是分析滚动/滑动接触的热弹流体动力润滑问题，并开发专家系统模型以帮助摩擦系统的设计过程。 该理论模型将分析润滑油膜和滚动/滑动元件内热量产生和消散的各个组成部分。 因此，确定了规定边界条件下的润滑剂工作温度。 摩擦系统中产生的压力和温度分布会在滚动/滑动元件中产生机械应力和热应力。 这些应力可能会在机器元件中产生并传播疲劳裂纹。 该理论模型将用于预测压力分布、温度分布以及由于不同几何形状、速度、负载和润滑剂的压力和温度而产生的机械应力和热应力。

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.
