• Abstract:

  In this work we intend to carry out a structural analysis of an off-road motorcycle chassis, as this sport is characterized by a high rate of mechanical failures in the vehicle and damage to the motorcyclist's physical integrity. All structural components of the motorcycle must resist high dynamic loads, due to impacts caused by maneuvers and radical movements. This project will be mainly based on finite element analysis, using Solidworks software, to validate and optimize the concepts presented in structural terms. For this, it is a basic condition to obtain the necessary mechanical properties, keep weight reduced to a minimum and manufacturing costs low. To analyze the structure, the finite element method (FEM) was used to obtain its structural response (displacements, deformations and stresses in the material). Based on the results, it was concluded that the motorcycle's rear fork containing the 2014 aluminum alloy is capable of resisting the analyzed boundary condition, without compromising its structural integrity.
