Abstract
En 中文
This study conducted experiments and analyses to identify the causes of failure in motorcycle suspension coil springs. The coating layer and metal surface adjacent to the spring fracture were damaged due to contact and corrosion. Furthermore, the breakage locations on each spring were similar. As a result of examining the fracture surface and surrounding area using SEM, no unusual features were observed other than the deformation and corrosion damage caused by contact at the crack initiation site. No microstructural factors directly contributing to the failure were detected, and the chemical analysis results conformed to specifications. In the micro-Vickers hardness test, no abnormal forming process factors, other than the work hardening caused by spring operation, were observed. Based on qualitative and quantitative analyses, the spring failure is attributed to repeated contact under severe operating conditions.
