1. First of all, the main factor influencing the spring's strength is its material, the higher the yield of the material in the zone, then, relatively speaking, the higher the fatigue strength of the spring, so to ensure that the fatigue strength of the spring should be first from the material of the spring On the study.
2. The quality of the spring surface has a great influence on the fatigue strength of the spring. The cracks and flaws caused by the spring material in the manufacturing process are often the most fundamental cause of the spring breaking due to fatigue.
3. The second is the production size of the spring. The larger the size of the material, the higher the possibility of defects. Therefore, the relevant spring manufacturer pays attention to the fact that when calculating the fatigue strength of springs, it is necessary to pay attention to the dimensions of spring production. .
4. The use of springs and storage environment, the influence of corrosive media on spring fatigue is extremely significant. When springs are used in corrosive media, they are caused by pitting or surface grain boundary corrosion. The source of fatigue; at the same time when the spring manufacturer in production, but also pay attention to the spring work in different environments, for the spring caused various effects.
Spring is a kind of mechanical part that all industries are currently using. It has a wide range of applications. For example, automobiles, machinery, aviation, and ballpoint pens used by everyday children are now indispensable in society. The kind of parts, however, we know that the force of the spring sometimes becomes very weak, and the use effect is not very good. Then, what are the main factors that affect the use of the spring?
