If the elastic properties of the element are non-linear, the stiffness is no longer constant but changes with increasing load. Nominal stiffness the stiffness given when the resilient element is designed and calculated is called the nominal (or rated) stiffness. It has an error from the measured stiffness of the element, particularly an elastic element having nonlinear elastic properties. The nominal stiffness represents the stiffness at which point on the curve, and is considered carefully. Generally, the nominal stiffness should not be directly calculated by design, but should be corrected by testing the product prototype. The stiffness tolerance is the allowable dispersion range of stiffness when tested on a batch of spring elements. The stiffness of each element of the stainless steel metal hose is different for the same batch of elastic elements, and has a dispersion range. In order to ensure the usability of the element, a limit must be imposed on the range of the stiffness dispersion. For the elastic sensitive element, the requirement of the rigidity tolerance is limited within +/-5% of the nominal value; for a typical engineering bellows-like elastic element, the tolerance for stiffness may be limited to within +/-50%.
