MENDOZA-FERNANDEZ, Abdel; GOYTISOLO-ESPINOSA, Rafael; CABELLO-ERAS, Juan José  e  JIMENEZ-BORGES, Reinier. Calculation method for the determination of stresses in right-wing flywheels. Dyna rev.fac.nac.minas [online]. 2018, vol.85, n.204, pp.98-107. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v85n204.64478.

This research deepens on the methods to the solution of the hyper static systems applicable for the assessment resistance of flywheels which are applied to a flywheel of a hammer mill. The results of the analytical methods were validated through a Finite Element Analysis, the results show differences minors than 10%. The equivalent strength in the rim is almost zero in the middle plane of the beam and increases as it moves away from it, and remains constant throughout the rays. It was also observed that in all the studied cases the equivalent tension decreases when the number of rays increases because of the flywheels stiffness increases. Also, graphics tools are obtained to a fast determination of the equivalent tension in the rim according to the number of rays and the speed of operation.

Palavras-chave : hyper static systems; equivalent stress; flywheel; rim; rays.
