Impact: the maximum vertical loads induced by a moving load will often exceed those produced by an equivalent static load. This is commonly called Impact where I¼(impact factor) defined as the ratio of the additional load (total dynamic minus static) divided by the equivalent static load; experimental studies in the past have revealed the common values of the impact factor (Figure …

mill suppliers do not state the dynamic loads generated by an operating mill, ie drive train and charge related load variations. Such a document may be far simpler to comprehend, however will cause problems when it comes to correctly designing the foundation. Consideration of static x, y, z loads is not enough; capacity.

A dynamic load is any load that changes over time. These type of loads exert forces onto a structure that are often much greater than their static equivalents. For example, someone jumping up and down will exert a greater force on the floor than someone standing still. Causes of dynamic loading can include anything from people moving around to ...

A typical dynamic mode of the plate mill stand drives is shock loading at the time of roll biting. The analysis of the Mill 5000 reversing stand drive torque and speed waveforms has shown that in this case, the drive enters the torque limit mode. On the transmission shaft, damping torsional oscillations occur which are two or more times higher than the steady rolling torque. The …

Mismatching of the speeds of the rolls in the vertical and horizontal stands leads to a dynamic reduction in the speed of the rolls of the vertical stand Δv V dyn I V dyn by 57% (from 917 to 1440 A). In the horizontal rolls, velocity Δv H st I H st from 325 A (no-load current) to 12200 A (the steady-state value), with a subsequent shock-related increase (surge) to 14580 A. …

However, because of system stability events which involve load response dynamics, load modelling has been gaining more interest from both the research and industry sectors [1 – 7]. As industrial loads are normally large in size and complex in nature, their dynamic behaviours play an important part in terms of system stability [1, 3]. Thus ...
