In electromechanical products, the most used springs are:

 1) Automobile-based motor vehicle springs;
 2) Springs for electronic products based on household appliances;
 3) Optical springs based on cameras, copiers and cameras.
The spring of motor vehicles is mainly developed in the direction of high strength to reduce the quality; the spring of electronic products is mainly developed in the direction of neutralization; and the springs of optical devices are mainly developed toward the direction of both high strength and small size. The corresponding spring design methods, materials and processing techniques have all developed.

 A, the development of spring design
At present, the widely used spring stress and deformation calculation formula is derived from the material mechanics. Without certain practical experience, it is difficult to design and manufacture high-precision springs. With the increase of design stress, many previous experiences no longer apply. For example, after the design stress of the spring is increased, the helix angle is increased, and the fatigue source of the spring is transferred from the inside of the coil to the outside. To this end, sophisticated analytical techniques must be used. The most widely used method is the Finite Element Method (FEM).

Vehicle suspension spring special
The sign is that in addition to having a sufficient fatigue life, its permanent deformation should be small, that is, the anti-relaxation performance should be within the specified range, otherwise the center of gravity of the vehicle body will shift. At the same time, consider the effect of environmental corrosion on its fatigue life. As the vehicle maintenance period increases, more stringent requirements are imposed on the permanent deformation and fatigue life. Therefore, a high-precision design method must be used. The finite element method can predict the influence of spring stress on fatigue life and permanent deformation in detail, and can accurately reflect the relationship between spring fatigue life and permanent deformation.
