GARCIA, Ricardo Ferreira; QUEIROZ, Daniel M. de  e  DIAS, Gutemberg Pereira. ANALYSIS OF STRESS APPLIED IN A FORAGE HARVESTER KNIFE. Rev. bras. eng. agríc. ambient. [online]. 1998, vol.2, n.2, pp.219-223. ISSN 1807-1929.  https://doi.org/10.1590/1807-1929/agriambi.v02n02p219-223.

The analysis of stress applied in the knife of the JF 90 Z 10-forage harvester was evaluated in this study. A model to analyze the knife stress was developed using ANSYS 5.3, a finite element type software. Model verification was done by comparing ANSYS results to analitical results for a simpler problem. A close agreement was found between the developed ANSYS model and the analytical solution. To simulate the application of the forces applied in the knife, a rotor rotation of 1,450rpm and a rotor cutting power of 29,000W were considered. The maximum equivalent stress found was 144.6MPa and its position was in the knife cut edge.
