为了便于分析研究设备的磨损状态等相关性规律，研制了基于计算机的磨粒图像轮廓识别和轮廓分形参数分析软件。在获取磨粒图像链码的基础上，利用该软件对销一盘试验机采集的磨粒进行分析，发现磨粒分形维数的变化与磨损状态有一定对应关系。该软件为磨粒分形特征与磨损状态相关性规律的研究，提供了简便快捷的手段。

In order to analyze the correlation laws between fractal feature and equipments worn states, the software used to identification particles contours and to compute the fratcal dimension of the particles contours is programmed based on the computer. This paper presents the fractal parameter and its calculation method of the worn particles based on particles contours' chain code. Some worn experimental tests were carried out at the pin on disc experiments and the worn debris were sampled at varies running in stages. It is found that, when the subroutine be used to compute the particles' parameters, the change of the fratcal dimension of the worn debris is corresponded to the machine worn states at different running in stages. The results show that it is convenient to compute the fratcal dimension of the particles contours with this subroutine. The software offers effective and simple methods in researching the correlation law between fractal feature and equipments worn states.
