Sažetak
The mechanisms are systems of moving parts that perform some function. One of their main advantages is converting the input forces and movements into a desired set of output forces and movements. The mechanism movement simulation is described in this paper. The solution includes calculation of velocities, accelerations and overall performance analysis. Numerical simulation of model mechanism was performed in the software package SAM. The velocities optimal for the drive element and the initial position of mechanism were given for initial conditions. All velocities and accelerations of mechanism points in this position were calculated. Results of computer simulation were compared with the results obtained by vector method. By comparison of the results it was found that the deviations were small, therefore it was concluded that the simulation was successfully performed.
