摘要
发动机主轴承油膜厚度的测量，对于发动机润滑系统的设计改进及润滑油品质的评定等是很有意义的，但受结构空间等因素的限制，也是很困难的。本文介绍采用自行开发在线测量系统，使这一问题得到较好的解决，并获得了一些重要结果。
The Measurement of oil film thickness of engine main bearing is very important to the design improvement of engine lubricating system and the evaluation of the quality of lubricating oil.However,it is quite difficult due to the limitation of factors such as structure,space,etc..This paper briefs the self made on line system with which the problem is solved quite satisfactorily and some important results are obtained.
