Abstract

Fretting and fretting fatigue are important considerations to be made in the design and development of medium-speed reciprocating engines. Predictive capabilities for safe-life design often rely on very simple empirical parameters and experience. Practices are briefly reviewed, and opportunities for more sophisticated methodologies are highlighted. It is concluded that more research into fretting fatigue with complex load sequences are needed.

中速往复式发动机的微扰——对实践和机会的评论
微动和微动疲劳是中速往复式发动机设计和研制中需要考虑的重要问题。安全寿命设计的预测能力往往依赖于非常简单的经验参数和经验。简要回顾了实践,并强调了采用更复杂方法的机会。因此,需要对复杂载荷序列下的微动疲劳进行更多的研究。
