Dynamic Loads

Dynamic loads may also be classified as periodic and non-periodic loadings. When a loading repeats itself at equal time intervals then it is called periodic loading. A single form of periodic loading is either a sine or cosine function as shown in Fig. 1.1a.A vibration ...

The Dynamic Loads on Rolling Mill Drives

Abstract: This paper describes the simulation to determine the dynamic loads on two rolling mill drives, one a horizontal roughing mill and another an attached vertical edger. These drives experience excessive dynamic loads resulting from the torsional vibration of inertias and shafts with significant backlash from the gearings and couplings.
