Under normal load and operating conditions = 1 2 Under impact load or vibration operating conditions = 2 3 For best dynamic performance and service life aim for a >5 Dynamic load capacity is not a stand alone load rating but rather a parameter used in an equation to calculate the theoretical service life of a bearing system It
Under a static load a structure responds slowly and its deformation reaches a peak when the static force is maximum [1] • Dynamic loads Dynamic loads are applied suddenly to a structure often with rapid changes in magnitude and point of application Under a dynamic load a structure develops inertial forces in relation to its mass
The dynamic load is the cyclic force applied to the fan bearings when the gravity center of the dynamic parts hub shaft coupling or pulley does not match with the rotational center Like any centrifugal force the dynamic load is function of the rotor s mass the square of the rotational speed and the distance between the center of

A load may be classified as static or dynamic A vital and challenging job is determining the proper loads acting on a machine component If the working loads are not accurately estimated or predicted all stress and deflection analysis is useless and the component cannot perform as intended The loads operating on a machine component may be
Dynamic Load A dynamic load refers to the weight that is placed on an object and then put in motion For example a pallet rated for a dynamic load of 2000 lbs means you can put up to 2000 lbs of an evenly distributed product on the pallet Then the pallet could be placed on a conveyor system or be moved around a warehouse by a forklift
