Load/deflection curve
The load/deflection curve for a single disc spring is not linear, with its shape being rather a function of the ratio ho/t.
Figure 2 illustrates load/deflection curves as a function of the ratio ho/ or C4 x ho, f/tf
Design and actual load characteristics
When measuring the spring load using a load tester, the spring load is, for example, as shown in Figure 3.
When s/ho >0, 75, the actual curve will deviate more and more from the design curve because the disc springs will be in contact with each other or with the support plate, which results in a steady reduction in the length of the lever arm.
