Development of spring materials With the development of spring application technology, higher requirements are put forward for spring materials. It mainly focuses on improving fatigue life and anti-relaxation performance under high stress; Secondly, according to different applications, it is required to have corrosion resistance, non-magnetic, conductivity, abrasion resistance, heat resistance, etc. For this reason, in…

Development of spring design At present, the widely used spring stress and deformation formulas are derived from the mechanics of materials. Without some practical experience, it is difficult to design and manufacture high-precision springs. With the increase of design stress, many previous experiences are no longer applicable. For example, as the design stress of the…

Development status of spring technology In electromechanical products, there are various springs, mainly including the following types 1. Supporting spring and maintenance spring mainly for automobile, motorcycle, diesel engine and gasoline engine. Such springs include valve spring, suspension spring, damping spring and clutch spring, etc., with large consumption, accounting for about 50% of the spring…
