VALDES HERNANDEZ, Pedro A  e  MARTINEZ RODRIGUEZ, Arturo. Software for rational determination of the forage chopper work parameters of drum type with manual feeding. Rev Cie Téc Agr [online]. 2011, vol.20, n.2, pp.80-85. ISSN 2071-0054.

The user´s manual of software "RACPIC" for theoretical calculation and evaluation of the forage chopper work parameters the drum type with manual feeding, is presented. The software allows the prediction of the rational parameters of this machines on the base physical-mathematical modelation of its technological process, in such way that the existent relationships are obtained among the main exit parameters as they are: the caliber of the processed shafts particles, the flow or productivity of the chopper, the forces taken place during the interaction knife - vegetable mass - kitchen knife, the useful and total power, in function of the variation of feeding ramp angle, the longitude of the kitchen knife and the quantity of shafts fed to chopper. The software also facilitates through its grafication, the comparison of the theoretical results with those experimentally obtained for the case of the prosecution of thick shafts, being corroborated the validity of the theoretical model for the design and improvement of these machines.
