Diseño, modelación y construcción de un prototipo de chasis para motocicleta con fines de producción nacional.

Abstract

The design and construction of a prototype motorcycle chassis, which will guide the productive sector of motorcycle parts and also a contribution to increase the percentage of domestic components in the assembly motorcycles contributing to change the country’s productive matrix was performed. In the chassis design are considered geometric features and elements that will be mounted on it, as well as manufacturing materials which were tested to determine the appropriate arriving as the mechanical properties and chemical composition. Geometric design with simple open chassis cradle analyzes were performed based on the phenomena of acceleration, deceleration or braking with the front and rear wheel, maximum speed cornering, determining the stresses that are generated in the chassis; which they were used in the analysis by finite element software, obtaining acceptable results in: security factor, effort and maximum deformation. During construction of the chassis it was necessary to build a jig mounting support and facilitated the proper positioning of elements in welding processes. END performed (NDT) to welds, then held the painting process according to technically defined processes. Finally the prototype costing of materials including construction, manufacturing processes (turning, forming, welding, painting, etc.), concluding with the feasibility of production of chassis materials and domestic technology and also with a suitable design.
