摘要: 通过对典型环形机械零件同步器齿环和齿轮的分析,发现环形零件具有不规则自相似性,因此采用分形理论及分形维数算法(结构函数法和盒子法)计算同步器齿环和齿轮的分形维数,证明了用分形理论可以表示环形零件的测量特征。进一步研究基于分形测量特征的环形零件缺陷识别问题,结果表明:盒子法相比较于结构函数法识别缺陷同步器齿环具有更好的稳定性和准确性;结构函数法相比较盒子法识别缺陷齿轮具有更好的稳定性和准确性;不同的环形零件利用不同的分形维数算法,可以计算出其不同的测量特征。

关键词: 同步器齿环, 齿轮, 分形维数, 结构函数法, 盒子法

Abstract: The analysis of typical mechanical parts synchronizer ring and gear shows that annular parts have an irregular self-similarity.Therefore,the use of fractal theory and fractal dimension algorithm (structure function method and the box method)to calculate the fractal dimension of synchronizer ring and gear,proved that measured characteristics of annular part can be expressed by fractal theory.Further research papers based on fractal characteristics of measuring parts of the annular defect identification problem.The results showed that:compared to structure function method to identify defects synchronizer ring,box method has better stability and accuracy;structure function method has better stability and accuracy to identify defects gear;using different parts of the ring different fractal dimension algorithm can calculate the different measurement characteristics.

Key words: synchronous gear ring, gear, fractal dimension, structure function method, box method
