【 摘 要 】

The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically called rigid memory mechanisms, are mechanical transmissions widely used in the economy for many years. They are widespread in the medical world, being used in various medical devices and in medical engineering, they also meet most of the vehicles mounted on their engines, with internal combustion, as valve distribution mechanisms, in the world of industrial robots, but also in the Of mechanical transmissions. The cam and follower mechanisms have spread the first time they were used in the wars of tissue (automated tissue machines). The distribution mechanisms could not be replaced with other electromechanical systems because they did not have the necessary resistance and reliability.
