Finite Element Research on Dynamic Characteristics of CNC Turret Punch Beam

FEA modeling method of stamping machine has been carried out using "Yoshimura Yoshitaka" method for studying its dynamic characteristic, it provide an easy method for dynamic characteristics analysis to determine characteristic parameters. To validate the FEM results, modal parameters of the beam under the work conditions were tested based on the theory of modal analysis. The FEM results are in good agreement with those from test measurements. The comparison has demonstrated that the FEM can model the beam vibration effectively and accurately, the calculate method is advisable to the engineering application.
