Simulation research on the kinematic behavior of virtual model of agricultural machinery

This paper describes the use of simulation in the design of agricultural machinery. It allows to define the kinematic behavior of the designed machine. 3D models of tractor and cooperating universal tool for strip tillage and model of cultivation aggregate with hitch to the drill were developed to conduct the kinematic analyzes. Simulation results are presented graphically on the graphs, which show the values of the measured parameters. The executed research defined reaction forces between machine and three-point hitch linkage of the tractor, the tractor stability and impact of changes in position of drawbar coupling parts on the selection of hydraulic cylinder. It was demonstrated the stability of the tractor when driving through the obstacle and the correct selection of the hydraulic cylinder, which ensures the correctness of the process of folding and unfolding.
