Diseño, análisis y construcción de un prototipo de tanque de combustible de motocicleta con fines de producción nacional.

Abstract

The design, analysis and construction of a motorcycle fuel tank prototype was made, it will be used for future design and manufacture studies in order to contribute with the pertinence to Automotive Engineering School in the study and generation of technologies for the obtaining of motor vehicle parts and to be integrated with the change of the production matrix. To execute the work, the tank of Suzuki GN 125 motorcycle was examined as an initial design, it was applied the reverse engineering by using the 3D scanner determine geometric characteristics, and to characterize the material in order to compare the mechanical properties with materials of national production. The initial model was redesigned emphasizing in the driver’s ergonomics and in the descriptive study; once the efforts and pressure that affect the tank design were obtained, it was applied and analysis of Infinite Elements to simulate the conditions described in JASO publication Nº T906-2 international regulation of the JSAE JASO STANDARS. By being an exploratory investigation, eved the modeling of the dies for a hypothetic production in series was achieved, meanwhile for the construction of a prototype there were used materials as wood and fiberglass, considering that the ASTM 1006 steel is the most used tank construction material. Reaching the goals, the JIS G 3141 SPCC national production steel has mechanical properties satisfy all the experimental proofs of impact, pressure and free fall that were simulated in the tank causing little deformations which never exceeded fluence limits nor the rupture limit of the material resulting in a secure design. With the experimental proofs, it was possible to obtain a minimum security coefficient of 2, reaching an adequate manufacturing cost.
