Research on Distribution Characteristic of Dynamic Forces and Moments for the Oscillating Ink Mechanism of Press

Distribution characteristic of dynamic forces and moments for the oscillating ink mechanism of press is the fundamental of Finite Element Analy sis (FEA) to the wall of the press. Based on the kinetostatic method, the dynami cload model to the motion pairs of the oscillating ink mechanism isderived. Fur thermore, the analytical formula of force and moment is given by elimination method. The dynamic load's feature between the motion pairs of the mechanism is analyzed with examples. It is shown that sudden change of the forces and moments between motion pairs takes place at the position changing direction of the oscillation roller, leading to the shock and vibration of the wall and printing troubles.
