Parabolic spring
A parabolic spring is a special type of leaf spring .
In order to achieve a constant voltage distribution has a parabolic spring (similar to a trapezoidal spring) a variable along the length of area moment of inertia in that the thickness of the spring according to a parabola changes: .
With
- l: Young's modulus
- b: width
- : maximum thickness
- l: length up to the maximum thickness.
