Abstract
The suspension system of a motor vehicle is always complex to size. In order to do so, it is necessary to take into account several factors such as efficiency, safety and comfort, for example. With the goal of designing a double-A type frontal suspension system that is safe and effective in overcoming obstacles, the initial step is to study which phenomena directly interfere in the suspension. Among the various phenomena, the forces generated by free fall, lateral force during a curve and braking are the ones that most require the whole system. Of the possibilities to improve the damping of these forces, the possibility discussed in the present article is to size the forks of the suspension using the topological method in order to reach the best geometry for the suspension, associated to the lower weight. This work aims to define all the loads and then pass analytical analysis to numerical, where a system of double suspension type A will be simulated by finite elements, with the intention to measure the tension and the resulting deformation of these requests. With the result of the simulation, it is possible to optimize by means of a topological analysis the geometry of the suspension forks, creating an innovative sizing method that guarantees a damping that does not compromise the pilot's health neither the useful life of the vehicle structure.
