Form factor
The form factor is a geometric measure for the shape of
an elastomeric bearing deined as the ratio of the loaded
area and the area of sum of the perimeter surfaces.
Deinition:
Form factor =
Loaded area
Loaded area
Perimeter surface area
Perimeter
surface area
I·w
2·t·(I+w)
For a rectangular shape: q =
(l..length, w..width, t..thickness)
Perimeter surface area
The form factor has an inluence on the delection and
the static load limit respectively.
Elastic Sylodyn®-bearings are considered as
Full surface bearing: Form factor > 6
Strip bearing:
Form factor between 2 and 6
Point bearing:
Form factor < 2
Inluence of the form factor on the static load limit
for a homogeneous material
