6 Form factor The form factor is a geometric measure for the shape of an elastomeric bearing defined as the ratio of the loaded area and the area of sum of the perimeter surfaces. loaded area definition: 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 influence on the deflection and the load limit respectively. Elastic Sylodyn-bearings are considered as full surface bearing: form factor > 6 strip bearing: form factor between and 6 point bearing: form factor < Influence of the form factor on the deflection at the load limit for a homogeneous material reference value: form factor q= Influence of the form factor on the load limit for a homogeneous material reference value: form factor q= deviation of deflection [%] % 8% 6% 4% increase of deflection load limit [N/mm ]..4 decrease of load limit increase of load limit % % decrease of deflection.8 -% form factor form factor 6
