Parametric identification on a dynamic behavior model for a forging machine

Abstract

Abstract. Dynamic models using masses, dampers and springs have been developed to represent the behavior of energy piloted machines. These models were proven to estimate more accurately the required amount of energy to forge a part. But how to identify the parameters of the model to accurately represent the behavior of a specific machine? In this study, the case of a strike without billet on a screw press is investigated, different target functions are tested to identify the model parameters and a sensitivity study of the optimization is performed. Results are encouraging.
