Abstract
Models using masses dampers and springs have been developed to represent the dynamic behavior of forging machines piloted by energy, like hammers or screw presses. But until now, most of these models are describing an entire production system including both the forging machine and its tools. Thus, if the same machine is used but with different tools, the entire model may be wrong and has to be completely redefined. This work proposes a first step toward the dissociation of the tools from the machine in the dynamic model of a screw press and its tools. Bare strikes, without billet, were performed on a screw press with two different tools configurations. The load and ram acceleration signals as well as their Fourier transforms were compared for the two different tools configurations. A two degree of freedom model is identified, with a first mode found to be press dependent and a second mode that is tool dependent. The masses, stiffnesses and dampers model’s parameters were identified for both tools configurations and largest deviation were observed for the second mode parameters. Thus, confirming the possibility to dissociate the press from the tools in the dynamic model.
