The dynamic characteristics of the MG-H series large-scale billet dressing machine hydraulic loading system are studied deeply. The mathematical model of the loading system is established, the dynamic stiffness of the loading system is analyzed, and the self-weight and Coulomb friction of the loading mechanism Influence of loading system dynamic stiffness. The measures to improve or improve the dynamic characteristics of the loading system are proposed, and a great deal of simulation and experimental results are given.
