DYNAMIC AND ENERGY MODELING OF THE ACTIVE ELEMENTS FROM COMPLEX AGGREGATES TO SOIL PREPARED

Abstract

Tis paper presents a method to measurement the forces, the stress and strain that occurring to the active organs of the complex aggregates for to the soil prepared. For measuring the torque, the stress, the angular speed of the tractor PTO, shaft a torque and angular speed transducer was performed. It was mounted between tractor PTO and agricultural machinery. For determining the distribution of the tractor power on to the driving axis a torque and angular speed transducer was performed and mounted on the cardan shaft transmission of the driving axles. For measurements the forces and strain that in agricultural machinery performed, was construction a intermediate frame with tens metric rings and angular transducer. This equipment is enabling to simultaneous measurement of the following parameters: connecting forces between tractor and machine, the torque transmied to the machine by PTO, shaft and the torques transmitted to the tractor driving axis.
