Simulación por elementos finitos y propuesta de modelo matemático del comportamiento dinámico de la suspensión posterior de una motocicleta de carretera tipo CUSTOM 125 CC.

Abstract

This Project has as purpose to analyze the rear suspension system of a motorcycle Using the finite element method, using the computer program Ansys, in addition to planting a mathematical model that governs the dynamic behavior of the suspension using the program computational Matlab. The analysis is carried out defining the geometries of the different elements that compose the suspension, its materials and available within the system, the forces acting on the system are determined during its operation and an analytical study is realized to know the behavior of the suspension, for dynamic analysis took into account two conditions, the first case is the state of normal braking, the second one is the braking thoroughly of the motorcycle. A comparison is made between cases before raised, of the deformation, the tension and the displacement, in which was obtained as a result that greater force will apply greater braking is deformation, strain and displacement. The mathematical model is based on the simplest version, it is possible to be mass each of the shock absorbers like a set-wharf, it is observed in the different graphs of speed, displacement, acceleration, that a greater force, the greater is the resonance frequency, agreeing with the study conducted using finite elements Ansys.
