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 2 t (I+w) perimeter surface area perimeter surface area The form factor has an influence on the deflection and the load limit respectively. Elastic Sylomer-bearings are considered as full surface bearing: form factor > 6 strip bearing: form factor between 2 and 6 point bearing: form factor < 2 Influence of the form factor on the deflection at the load limit for a homogeneous material reference value: form factor q=3 Influence of the form factor on the load limit for a homogeneous material reference value: form factor q=3 deviation of deflection [%] 10 % 5 % increase of deflection load limit [N/mm 2 ] increase of load limit 0 % 100 decrease of deflection -5 % 095 decrease of load limit -10 % form factor form factor 6
