Quarter Elliptical Laminated Plate Spring Stiffness Online Calculator

App description

\(k=\frac {E×n×b×t^3}{6×L^3}\)

• k = hardness
• E = Young's modulus
• n = number of blades
• b = blade width
• t = blade thickness
• L = span

Usage example

Input data:

Young's modulus (E)---15Nm^-2;

number of layers (n)---40;

width (L)---5m;

slice width (b)--- 8m;

sheet thickness (t)--- 4m.

Click "Calculate" to display the results.

Output results:

Hardness (k): 409.6Nm^-1
