The performance index of the disc-type welded vacuum bellows is the load value required to produce a unit displacement of the metal bellows or other elastic elements, which is called the stiffness of the element, which is generally represented by "K". If the elastic properties of the element are non-linear, the stiffness is no longer constant, but changes as the load increases. For general engineering bellows-like elastic elements, the stiffness tolerance can be limited within +/-50%. The stiffness of the bellows is divided into axial stiffness, bending stiffness, torsional stiffness, etc. according to the nature of load and displacement. In the application of bellows, most of the stress conditions are axial loads, and the displacement mode is linear displacement.
