| With the development of high-speed press on speeding up and lightweighting, it causes the augmentation of inertia force and component's flexibility. The vibration problem caused by inertia force and the output error caused by component's flexibility are one of the assignment which are researched at present. On this problem, the following have been studied profoundly in this paper.Firstly, the inertia force of actuator of high-speed press has been predigested. In this paper, some balanced scheme have been given by exerting correlation theory of dynamic balance, the perfect balanced scheme has been chosen .The inertia force balanced after decreased much compared to which was not balanced before. This study method can furnish reference for other press's dynamic balance.In this paper, based on the theory of mechanics of vibration and elastodynamics , the kinetic model has been built up and the dynamic differential equation of high-speed press has been derived on the base of regarding pillar as elastic body. Then the effect of the parameter of high-speed press to the amplitude and natural frequency has been studied. This study can provide theoretical foundation for isolating vibration. And the displacement response have been supplied through using Simulink of MATLAB. It can provide a simple simulation method.The finite element model has been given and the dynamic differential equation has been derived on the base of regarding crank and linkage of actuator as elastic body in this paper. Then the character of natural frequency has been studied. It can provide theoretical foundation for avoiding resonance and farther analysis.Finally, the multi-rigid and rigid-flexible coupling virtual prototype models have been built up through Solidworks, ADAMS, ANSYS software. The difference of regarding the linkage aselastic body before and after has been compared. This study can provide a new approach for the output accuracy under the case of rigid-flexible coupling model.
