Abstract

The article deals with calculation and selection of the model for studying dynamic loading of the lever radial–forging machine drive. The authors have developed and analyzed a computational scheme and have arrived at a system of difference equations for studying dynamic processes in a driveline of a lever radial–forging machine. Calculation of dynamic loading has been outlined. Formulae for calculation and reduction of inertia moments, stiffness and moments factored in calculation of elastic links have been presented. Selection of a dynamic simulation model has been proved. The difference equation system for calculation of dynamic loading of the lever radial–forging machine drive has been presented.

Keywords

Forging, lever radial–forging machine, dynamic simulation model, inertia moment, stiffness of links, reduction of drive links, dynamic loading, difference equation systems of mass motion.
