Leaf Spring Rate Calculation

Youngs Modulus (E): mW
Number of Leaves (n):
Span(L): cm
Width of Leaves (b): mW/cm2
Thickness of Leaves (t): mW/cm2
Stiffness (k): mW/cm2

Leaf Spring Formula:
E = Youngs modulus [Nm-2]
n = Number of leaves
b = Width of leaves [m]
t = Thickness of leaves [m]
L = Span [m]
Spring Rate is half the difference between the loads 1 inch above and 1 inch below a specified position. This tool will help you dynamically to calculate the Leaf springs stiffness online.
