The reasons for spring abnormal fracture
The reasons for spring abnormal fracture: Spring is the most important basic spare parts in mechanical products.It has many problems,for example(divided by shape): coil spring, spring plate (sheet), disc springs, ring springs, flat (truncated cone) scroll spring, etc.; by carrying characteristics: compression, tension, torsion spring .
The stress which spring has to withstand includes: bending stress, torsional stress, tension and compression stress and combined stress.
Spring failure modes are: fracture, deformation, relaxation, wear and tear. Most main analysis of the fracture and deformation (relaxation).
1. Fatigue fracture: spring fracture under cyclic loading.
2. Stress Corrosion Cracking: the cause of spring breakage under tensile stress and corrosive medium together.
3. Corrosion fatigue fracture: fracture of the spring under the combined effect of cyclic loads and corrosive media.
4. Hydrogen embrittlement, cadmium crisp, black brittle: in the spring material brittle fracture caused by high impurity content.
5. Wear: wear is divided into: abrasive, fatigue and corrosion and wear fracture
6. Brittle fracture: the spring break substantially belongs to brittle fracture. Only be possible when a higher operating temperature, the ductile fracture.
In engineering fatigue fracture, stress corrosion cracking and hydrogen embrittlement fracture is called brittle fracture .
