GONZALEZ, Y. E.; VIOLET, M. A.  and  AGUDELO, H. D.. Application of the design for manufacturing and assembly method to the chassis of a recumbent three-wheel human-powered vehicle as alternative transportation in the city of Montería. Entre Ciencia e Ingenieria [online]. 2019, vol.13, n.25, pp.35-44. ISSN 1909-8367.  https://doi.org/10.31908/19098367.4012.

This work presents the design of the chassis of a human powered vehicle (HPV) type recumbent of three wheels through design studies based on finite element analysis provided by Solidworks® tool. The methodology of design for manufacturing and assembly (DFMA) promoted by Bootrhoyd was implemented, for which, the design of a model built in 2014 by mechanical engineering students called VTHR-1 was used as a comparison element to determine the effects produced by this methodology in the redesign of the chassis. As a result, a safety factor of 1,6 and an estimated life of 4,293x10^5 cycles, in addition, a decrease of 69% in the complexity of the assembly of the power transmission system was estimated, a 32% reduction in manufacturing cost and a structure 19% lighter, which translates into an indispensable method when it comes to directing the project as an alternative transportation mean in the city of Monteria.
