What is the characteristic curve of stainless steel spring?

The relationship between load and deformation of stainless steel spring is called spring characteristic curve. The slope value of the characteristic curve reflects the stiffness of the stainless steel spring. The characteristic curve of stainless steel spring with constant stiffness is a straight line, while that of spring with variable stiffness is a curve.

What is the purpose of strength calculation and stiffness calculation of stainless steel spring?

calculation Stainless steel spring The purpose of strength is to ensure that plastic deformation and fatigue failure will not occur when the spring works. The purpose of spring stiffness calculation is to ensure that the spring has the required elasticity.

There are two cylindrical spiral extension springs. If they are made of the same material, stainless steel spring wire diameter, end structure, etc., only the effective turns are different. Try to analyze its strength and stiffness.

When determining the cross-section shape and size of materials, the size series specified by national standards and ministerial standards should be preferred, and non-standard material series should be avoided as far as possible. Priority should be given to small and medium-sized springs, especially spiral tension springs. The results show that the strengthened lead bath isothermal cold drawn steel wire and oil quenched and tempered steel wire have higher strength and better surface quality, and the fatigue property is higher than that of ordinary quenching and tempering steel wire. The process is simple, the process is good and the quality is stable.

The material cross section of coil spring should be preferably circular. The materials with square and rectangular cross-section have strong bearing capacity and good impact resistance. Miniaturization also allows them to come from fewer sources. And the price is higher, unless there is a special need. Usually, this material is not selected as much as possible. In recent years, flat round steel wire has been developed to replace trapezoidal steel wire, and good results have been achieved.
