Leaf Springs Calculator

Leaf spring, commonly used for the suspension in wheeled vehicles. The term is also used to refer to a bundled set of leaf springs. As the spring flexes, the leaves slide over each other; the resultant friction provides a dampening of the oscillations produced by large spring deflections.

Leaf Spring Formula:

 k=8Enbt3/3l3

where,

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.
