A new measuring apparatus with an optical particle sensor was studied in order to diagnose the lubricating conditions of tribo-conponents at real-time. Following results were obtained.1. Three types of laser beam particle sensor were constructed and their properties were tested in detail. The particle sensor using a selfoclens was found to be most useful. A circuit and data acquisition system which can measure the output signals of particle sensor was completed.2. The properties of our developed apparatus were examined by the measurements of the glassbeads (20 mum and 40 mum in diameter) in water and of the severe wear particles of brass in lubricating oil. The reliability of our measuring system was confirmed.3. The wear particles in lubricating oil in which was used in the wear tests of bearing metal (LBC3) were monitored at realtime using our measuring system. The variations of wear particles with sliding distance or contact load were found to correlate to those of wear loss.From these results, it is found that our developed optical particle sensor and apparatus is useful for lubrication diagnostics. The fruit of this study has reached our objective of research.

研究了一种带有光学颗粒传感器的新型测量装置，以实时诊断摩擦部件的润滑状况。得到如下结果： 1．构建了三种类型的激光束粒子传感器并详细测试了它们的性能。使用 selfoclens 的颗粒传感器被发现是最有用的。完成了可测量颗粒物传感器输出信号的电路及数据采集系统。 2．通过测量水中的玻璃珠（直径 20 微米和 40 微米）和润滑油中的黄铜严重磨损颗粒来检查我们开发的设备的性能。证实了我们的测量系统的可靠性。 3．使用我们的测量系统实时监测轴承金属 (LBC3) 磨损测试中使用的润滑油中的磨损颗粒。磨损颗粒随滑动距离或接触载荷的变化被发现与磨损损失相关。从这些结果可以看出，我们开发的光学颗粒传感器和设备对于润滑诊断很有用。本研究的成果达到了我们的研究目的。
