Fretting in medium‐speed reciprocating engines—Comments on practices and opportunities

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.
