Abstract

In this paper the fatigue analysis of the structural components of a high-speed press is presented. The fatigue analysis is based on the results of a hybrid multi-body simulation. During the hybrid multi-body simulation the press is virtually loaded by the forces occurring while cutting high-strength steel. The hybrid multi-body simulation was coupled with a durability software package for the fatigue analysis. A high cycle stress approach was applied for the fatigue analysis of the press frame, ram, con rods and eccentric shaft. In addition, critically dimensioned test structures were designed, manufactured and assembled to a highspeed press at the Institute of Metal Forming and Metal-Forming Machines to validate the fatigue analysis of the components of the press. The test structures were loaded due to the cutting of high-strength steel until crack initiation was detected by means of the dye penetrant inspection. The predicted and experimental determined fatigue life correlated. The simulation is based on design data and no calibration of the model was performed.
