Experimental and Analytical Investigation of Tribo-Contacts in Situ

将开发一种多用途仪器，用于在正常和严重操作条件下原位测量摩擦接触（滚子轴承，球轴承等）的压力和温度，包括4 GPa的赫兹压力载荷。数据收集工作将与建模工作并行进行，以确定接触处产生的总热量作为这些操作参数以及滑移、流体性质、表面涂层等的函数。该模型将提供接触区压力和温度分布以及牵引力的详细信息。

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.
