摘　　要：以频谱分析为理论基础 ,以动态测试为手段 ,采用数字信号处理技术提取滚动轴承摩擦副表面损伤的特征信息 ,通过时域和频域分析 ,即可判别各摩擦副 (外环、内环、滚动体 )表面的损伤状况 ,从而实现了对滚动轴承摩擦副表面损伤故障的检测与诊断。该系统具有良好的人机界面 ,全部汉字显示菜单 ,使用方便 ;系统采用结构化模块设计 ,每一功能由独立的模块完成 ,经改进和功能扩展 。Based on the theory of frequency spectrum analysis, the feature information of surface damage on friction pairs of rolling bearing was collected during the dynamic tests. The system can differentiate the damage conditions of each friction pair (outer ring, internal ring, roller) through time and frequency domain analysis, thus realizing the test and diagnosis of surface damage. The system has a good man computer interface and all the menus are displayed in Chinese for convenient use in China. The system kernel is a PC486 computer and the software is written in Turbo C language. Modular design is employed and each function is completed by a stand alone model. After improvement and function extension, the system may be extended to pick up and analyse other vibration signals.
