6 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. Loaded area Deinition: Form factor = For a rectangular shape: q = (l..length, w..width, t..thickness) Loaded area Perimeter surface area I w t (I+w) Perimeter surface area 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 > Strip bearing: Form factor between and Point bearing: Form factor < Inluence of the form factor on the delection at the static load limit for a homogeneous material Reference value: Form factor q= Inluence of the form factor on the static load limit for a homogeneous material Reference value: Form factor q= Deviation of delection [%] % % % % Increase of delection load limit [N/mm ]..
