Abstract: Planar multi-bar mechanisms are widely used in the machinery industry. In this article, the hybrid mechanical press, a typical planar seven-bar mechanism is investigated. The dynamics mathematical model is established based on the simultaneous constraint method. On the basis of it, a relevant simulation is carried out by virtue of MATLAB. Thus, the dynamic response law and stress state for the key part (ram) of the mechanism are yielded. The simulation results show that this method is much more effective and efficient and provides a theoretical foundation and a better analytical approach of simulation for design and analysis of complex hybrid-driven mechanical equipment in the future.

Abstract: In this paper, a novel precision press is proposed, which is to combine the motion of a large constant speed motor with a small servomotor via a two-DOF mechanism, where, the constant speed motor provides main torque and motion requirements, while the servomotor contributes to modulations on this motion. The forward kinematic optimal design, electromechanical system dynamics modeling and simulation of this new mechanical press system have been presented here. The simple analysis of theoretical feasibility of the hybrid-driven press is investigated.

Abstract: Hybrid-driven five-bar mechanism that combines the motions of two characteristically different motors can attain the flexibility output movement. Its structure is simply and it has low cost. Therefore it is widely used manufacture fields. In this paper, the kinematics mathematic model of plane closed-loop five-bar mechanism is established according to the model-transforming method and closing-vector method. And expressions of its output movement parameters are attained. The output movement characteristic of hybrid-driven five-bar mechanism is imitated and studied. The results show that hybrid-driven five-bar mechanism which its geometry parameters confirmed can accomplish diversiform tasks through changing its input movement rule. Output movement track of hybrid-driven five-bar mechanism changes along with the original position of two input components changing. It indicates hybrid-driven five-bar mechanism can accomplish many group tasks at one time.
