Development of a Multibody-Based Dynamic Model of the Rear Hitch Subsystem of an Agricultural Tractor

This work deals with the implementation of the dynamic model of a subsystem typically present in agricultural tractors, namely a mechanical-hydraulic digital twin of the rear hitch. A multibody model of the rear hitch mechanical subsystem was developed in Simscape Multibody and integrated with the hydraulic system model developed in Simulink. Finally, a preliminary control logic to ensure the correct operation of the device was designed and its performance was assessed through simulations. The first simulation results appear promising.
