摘　　要：发动机润滑系统中流经摩擦部件表面的油液,携带了大量发动机运转的内在信息,通过对油液中的磨粒进行分析可实现发动机运行状态的监测。针对航空发动机的磨粒图像,主要研究了图像灰度化、二值化及形态学操作等磨粒图像处理技术,对已获得的磨粒图像利用MATLAB工具进行处理,定量分析了磨粒的大小、数目等参数。Because of the existence of the fluid,which carries the internal information of engine running,through the friction surface of the key moving parts in the engine lubrication system,aircraft engine condition monitoring can be achieved with the help of instrumental analysis of oil and wear debris.In view of the aircraft engine of abrasive image,the debris image processing algorithm is simplified by using MATLAB to process the debris image which have been acquired,and the abrasive particle morphology,size,number and so on can be analyzed quantitatively.
