 ## Calculation of the extension limit of the extension spring and the compression limit of the extension springs

he tension limit of a tension spring refers to the maximum tension that the spring can withstand. If this tension is extension springs will deform (failure)

His calculation method is: tensile spring stiffness coefficient (K), and then K=F/X, the elastic force F=KX, remember that X is the variable amount of displacement.

Elastic limit: the elastic deformation limit of the spring.

Elastic deformation: The spring can recover the deformation of the free length.

If the elastic limit is extension springs cannot recover its free length. At this time, it is not elastically deformed. In short, the spring is broken, exaggerated, and the spring is straightened. After straightening, you are pulling a wire. Therefore, after reaching the elastic limit, the tensile force will change, not constant.

The compression limit of a compression spring refers to the maximum pressure that the spring can withstand. If this pressure is extension springs will deform and fail. The limit force can be determined through design calculations, or based on known springs to replicate what it can withstand The ultimate pressure, his calculation method is:

The basic calculation formula of compression spring:

1. Spring diameter (mm)

2. Spring force (N)

3. Deformation (mm)

4. Shear stress (Mpsa)
