Projeto e análise estrutural de um chassi de uma motocicleta de competição categoria Moto 3

Abstract

This work aims to model and make structural analysis of a tubular chassis, with a triangulated structure, of a competition motorcycle category 3 (250cc), using chrome-molybdenum steel material, under the rules of the biannual Motostudent competition. The design of the chassis follows the requirements established by the Motostudent and its geometrical parameters seek to meet what is recommended for race bikes according to the specialized literature. The Modeling and structural analysis were performed in CAD / CAE Solidworks software and the situations considered were those that typically subject a chassis to constant stress during a race: braking, acceleration and slope. The loads resulting from these situations were calculated based on the center of gravity of the motorcycle and analyzed in a static way, taking into account the risk of runoff, the maximum displacement and the minimum safety factor that the structure presented in each of them.
