Spring characteristic curve
Spring characteristic curve
The spring characteristic curve is the relationship between the applied force and the deformation or displacement resulting from its action.
The spring properties depend on the elastic modulus of the elastomer and the geometric dimensions. Therefore, the binding identification of a bonded rubber spring is not the measured elastomer hardness in Shore A but the spring characteristic curve. A spring stiffness of ?12% means approximately ? 3 Shore A. For standard parts without special measures, the spring stiffness tolerance is ? 20%.
