Correction of Rolling Mill Mechatronic System to Limit …

Regulation in the mechatronic system of a DUO-300 rolling mill is investigated. The dynamics of an electric drive with a predictive PI controller in the current loop is analyzed. Methods are proposed for damping of self-oscillation and decrease in dynamic loads within the mechatronic system.

The Dynamic Loads on Rolling Mill Drives | Semantic Scholar

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.

What is Dynamic Loading? (A Definitive Guide) - TWI

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 ...
