MARTIN-CARVAJAL, Luís Orlando et al. Railroad cars for sugar cane transportation: determination of a new level of reconditioning to extend its life. Ingeniería Mecánica [online]. 2013, vol.16, n.1, pp. 52-58. ISSN 1815-5944.

The railway transportation of sugar cane is an economic variant and Cuba has the railroad infrastructure for this purpose. This paper deals with the shaft exploitation period increasing for the sugar cane cars, by obtaining a new reduced dimension in the stump diameter, under the most hard exploitation conditions. The calculation was carried out according to the railway standards, based on the Strength of Materials classic equations. The tensional and deformational level was also obtained, by using the Finite Element Method. The authors conclude that the minimal proposed diameter 95,25 mm responds to the necessary strength conditions, with a security coefficient, according to the required railway standards.
