Validación del modelo de cálculo de la potencia consumida por las picadoras de forraje del tipo de tambor con alimentación manual

the carried out investigation, it presents as objective to expose the obtained results during the validation calculation model of the consumed power for the drum type forage chopper with hand feeding, derived of the physical-mathematics modelation previously carried out of their technological process, taking like base for the experiments the variety sugar cane c323-68, being that of more use in cuba for the livestock feeding. the physical-mathematics modelation of the process allows the prediction of the power consumption, with errors non superiors to 4,3%, for a feeding angle between 6 and 14o, so much for the useful power as the total, with a level of significance of 1%, for rational values of the moment inertia drum. the rationalization of the moment inertia in the forage chopper machines of national production model mf-iima em-01 produced a decrease in the power consumption between 22 and 23%. being this modelation a valuable work tool that allows the improvement of the design of this type forage chopper.
