弹簧的故障模式主要有:断裂、变形、松驰、磨损。其中主析是断裂和变形(松驰)。
The failure modes of spring mainly include fracture, deformation, relaxation and wear. The main analysis is fracture and deformation (relaxation).
脆性断裂:弹簧断裂中绝大部属于脆性断裂。只有当工作温度较高时,才有可能出现塑性断裂。在工程上把疲劳断裂、应力腐蚀断裂及氢脆断裂等称为脆性断裂。
Brittle fracture: most of the spring fracture belongs to brittle fracture. Plastic fracture is possible only when the working temperature is high. In engineering, fatigue fracture, stress corrosion fracture and hydrogen embrittlement fracture are called brittle fracture.
疲劳断裂:弹簧在循环载荷作用下的断裂。
Fatigue fracture: the fracture of spring under cyclic load.

应力腐蚀断裂:在拉应力和腐蚀介质共同作用下引起弹簧断裂现象。
Stress corrosion fracture: spring fracture is caused by the combined action of tensile stress and corrosive medium.
腐蚀疲劳断裂:弹簧在循环载荷和腐蚀介质共同作用下发生的断裂。
Corrosion fatigue fracture: the fracture of spring under the combined action of cyclic load and corrosive medium.
氢脆、镉脆、黑脆:由于弹簧材料中有杂质含量过高引起的脆断。
Hydrogen embrittlement, cadmium embrittlement and black embrittlement: brittle fracture caused by excessive impurity content in spring material.
磨损:磨损分为:磨料、疲劳和腐蚀磨损断裂
Wear: wear is divided into abrasive, fatigue and corrosion wear fracture
