Abstract
The forging process involves the time-varying microstructure process of a forging and the macroscale motion of the hydraulic press machine (HPM). It is very challenging to model this process. In this paper, a simple and effective online modeling approach is proposed to meet this challenge. This proposed method first constructs a model set for the time-varying forging process. All parameters in the model set are then identified online by using process data. An error minimization-based match method is further developed to select a suitable model from the model set to reflect the present dynamic behavior of the system. Numerical cases and practical forging cases finally demonstrate the effectiveness of the proposed method.
