Abstract:

The present article has as main objective to model a four-bars mechanism to the drive system of a gel and minerals encapsulating machine. This model includes a kinematic and dynamic analysis using the vector loop method; defining as main input variable the angular displacement of the crank, the same that is connected to the motor. The accelerations in the centers of gravity (kinematic variables) of each element were related to the forces acting on the element. This was done using Newton's second law. Through the dynamic analysis of the mechanism, the necessary torque was determined to move it to the initial kinematic conditions. The torque was calculated using the Matlab software in the force equations for the entire range of motion; this means the complete cycle of movement of the crank. The result of torque obtained in Matlab was contrasted with the simulation software MSC ADAMS, where clear similarities were obtained between both results.
