A DYNAMIC ANALYSIS OF AN INDUSTRIAL C-TYPE ECCENTRIC PRESS THROUGH MODELING, SIMULATION, AND EXPERIMENTAL TESTING

Abstract

This study provides a comprehensive analysis of the dynamic behavior, modeling, simulation, and experimental validation of industrial C-type eccentric presses, offering critical insights into the optimization of press ground vibration. Through detailed modeling, the forces and vibrations experienced during operation were mathematically characterized, while simulations effectively demonstrated the system's behavior under varying operational conditions, and experimental studies confirmed the reliability of these models. The investigation also examined the impact of dynamic loads on machine foundations, analyzing single and double mass-spring systems using MATLAB simulations and analytical solutions to assess the influence of ground-foundation characteristics on the press's dynamic response. Prior to vibration isolation, the average peak ground displacement (PGD) was measured at 5.075 × 10⁻² mm, which decreased to 3.46 × 10⁻² mm and 2.7 × 10⁻² mm with the application of VI-1 and VI-3 isolators, respectively. The VI-3 isolator proved most effective, reducing transmitted dynamic forces to 2.57 × 104 N. Parametric analyses highlighted the system's sensitivity to isolator stiffness and damping ratios, with a stiffness ratio of 0.01 between the isolator and ground reducing foundation vibrations by approximately 46.8%. This research emphasizes the importance of dynamic modeling in designing and optimizing vibration isolation systems, making a significant contribution to enhancing vibration control in industrial applications.
