Simulation modeling allows researching a mechanism consisting of many links interacting with each other according to complex laws. In order not to write a model for each node of the investigated mechanism, it is advisable to use ready-made blocks of the Simulink application. To simplify the process of creating blocks responsible for the links of the mechanism, we used the Solidworks computer-aided design system. 3d models of each link were designed, kinematic connections between them were established. Thus, the mass characteristics of the links, their geometric parameters, moments of inertia and kinematic pairs were obtained. After exporting the model from the computer-aided design system to Simulink of the Matlab package, a basic block diagram was obtained which was supplemented with disturbing input signals, virtual oscilloscopes for characterizing, mechanical transmission units, etc. Based on the obtained coordinates of the frame links and the rotor knives, dependencies were constructed to determine the kinematics of their movement in three planes, which made it possible to clearly demonstrate the top and rear view of the mechanism under study in the considered time interval. The developed simulation model can be upgraded to study the dynamic characteristics of the mechanism.
