| Automatic Die Cutting Machine is one of important devices in packing printing industry and the moving platform mechanism is one of it's key die components, which performance has a direct effect on the stability and the speed of Die Cutting Machine. In this article, kinematics and dynamics characteristics of the moving platform mechanism of Automatic Die Cutting Machine was discussed for the sake of improving on the speed of Die Cutting and the moving platform mechanism. The following work was mainly finished:1. On the basis of rigidity hypothesis, a searching algorithm based on complex vector method was proposed. Complex vector method, searching algorithm and numerical value method was used to analyze kinematics characteristics of the moving platform mechanism. And the rule of movement of the moving platform in a period was obtained.2. Due to the change of press was unknown in the process of dieing, the model of the change of press was built. And a way of solving press by calculating the interference area of two platforms was proposed. Not only the change of press was got, but also the basis of dynamics analysiswas established.3. Dynamics characteristics of the moving platform mechanism in the case of unloading and loading was analyzed using Kineto-Statics, and the change of force of each component of the moving platform mechanism was gained in one period respectively.4. The effect of main body of Die Cutting Machine was imposed on press, especial the effect of the moving platform and the still platform, and corresponding improvement was provided, which in favor of improving the stability of Die Cutting Machine.5. The interface of the moving platform mechanism of Die Cutting simulation analysis software was presented which be programmed using MATLAB.By the researching of this thesis, not only the theoretical basis for deeply realizing the moving platform mechanism of Automatic Die Cutting Machine was given, but also the basis for improving this mechanism farther was established.
