Design and Manufacturing of a Pneumatic Driven Compression Spring Fatigue Machine

Abstract

Fatigue of the springs has not been studied widely in the industry. However, damage to the springs during operation can cause major irreversible damages. Since it affects the microstructural properties of the spring material to a high degree, fatigue analysis with various analysis methods cannot give a clear result. In this study, a multiple compression spring fatigue device simulating the real fatigue conditions was designed and produced. Machine design, production and control are also mentioned in detail. The electrical and solenoid operating system is also discussed.
