The spring force value is simply a calculation of the spring force. Spring force value refers to the elastic deformation of the spring will exert a force on the object in contact with it. This force is called the spring force. The spring force value is the calculation of the spring force.

(1) The compression spring is a helical spring that is subjected to upward pressure. The cross-section of the material used is mostly circular, but also rectangular and multi-strand steel. Springs are usually equidistant. The shape of the compression spring is cylindrical, conical, convex, concave, and a small amount of non-circular. There is a certain gap between the rings of the compression spring. The spring shrinks and deforms under external load and stores the deforming energy. For the design data of compression spring, in addition to the spring size, it is necessary to calculate the maximum load and load displacement size.

(2) Spring constant: expressed in K, when the spring is compressed, the load (kgf/mm) increases by 1mm;

(3) Spring constant formula (unit: kgf/mm) : 3G= rigid modulus of wire: piano steel wire g=8000; Stainless steel wire g=7300, phosphor bronze wire g=4500, brass wire g=3500, d= wire diameter do=od= outer diameter Di=id= inner diameter DM= node diameter MD= DO-d, n= total number of turns NC= effective number of turns = N-2, spring constant calculation example: For example, wire diameter =2.0mm, outer diameter =22mm, total number of turns =5.5 turns, steel wire material = piano wire
