A multi-purpose apparatus will be developed to measure in situ the pressure and temperature in tribo-contacts (roller bearings, ball bearings, etc.) under normal and severe operating conditions, including loads to Hertzian pressure of 4 GPa, velocities to 40 m/s and temperatures to 450 C. The data collection effort will run in parallel with a modeling effort to determine the total heat being generated at the contact as functions of these operating parameters as well as slip, nature of the fluid, surface coatings, etc. The model will provide detailed information on pressure and temperature distribution and on traction in the contact zone.

将开发一种多功能仪器，用于现场测量摩擦接触(滚子轴承、球轴承等)中的压力和温度。在正常和恶劣的操作条件下，包括赫兹压力为4 Gpa、速度为40 m/S和温度为450℃的负载。数据收集工作将与建模工作并行进行，以确定接触点产生的总热量作为这些操作参数以及滑移、流体性质、表面涂层的函数。该模型将提供关于压力和温度分布以及接触区牵引力的详细信息。
