摘要
利用电阻应变仪测定了高应力弹簧各有效圈上所受的力;利用扫描电镜观察其断口形貌,得出结论,造成弹簧端圈断裂原因有二,其一是弹簧端圈受力较大,其二是端圈接触部位的摩擦磨损引起的。
The force on available coils of the spring was measured by means of straingage. We found that the reasons of the fracture were the force on the end coil which was bigger than others and the rubbing wear at the end coils contacting part.
