钢的低周疲劳特性和表面疲劳裂纹的在位观测 - 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。 - Studying on the shakedown theories and plastic deformation of contact surface layer the shakedown of contact surface layer is related to the strain - hardening models of materials , such as isotropic hardening , kinematic - hardening , and mixed - hardening . the existing results based on experiments and theory show that the shearing strain behavior of contact surface layer caused by friction can be comparatively described with kinematic - hardening
研究中，围绕强化后接触表面疲劳问题，从强化模型选择、接触表层安定性存在的条件及其失效规律，进行了详细的概念定义、定理证明及推论演算等理论工作，为接触表面层安定性的数值模拟和疲劳分析奠定了理论基础。
