Abstract : in this article , the optimization of surface crack detection of speed reducer gear was made using fuzzy set theory , the result show that the rotation magnetic field is the best way of surface crack detection and lots of extending surface fatigue cracks were found in practice
文摘:采用模糊集的贴近度计算对齿轮表面探伤方法进行了优化选择，表明旋转磁场探伤是齿轮表面探伤的最佳方法，在实用中检测出大量的正在延伸扩展的表面疲劳裂纹。
The cam - follower is the main mechanism of the engine that carries out a series of accurate motions . its mild wear may gradually worsen the contact conditions . the probability for surface fatigue will then increase due to changes in the surface topography
凸轮?挺柱是内燃机中实现一系列精确动作的主要机构，其磨损会使接触条件恶化，由此产生的表面形貌的变化会使表面疲劳的概率增加，可能会对部件产生破坏性的影响，进行凸轮机构的摩擦学设计对提高内燃机的运行性能和延长使用寿命十分重要。
