Abstract
This work deals with the design of a 3-DOF active suspension mechanism that is able to control Vehicle Body Roll, Toe and Camber angles. This type of mechanism is able to improve handling performance and vehicle stability control, when it is compared to a passive suspension. Several mechanism designs were generated and one of them was described in this work. Firstly, the initial design of a product was chosen for all the components of the new suspension system. It includes the layout for the mechanism to be assembled on a vehicle. Then, using the commercial software ANSYS, a structural analysis was developed by applying the finite elements method. The input forces considered in these analyses correspond to the maximum values obtained considering a vehicle executing two different maneuvers. The first one is the fishhook maneuver, which was used to analyze the vehicle rollover tendency. The second one, a breaking test, was applied to analyze the vehicle behavior during hard breaking conditions. The results show that the mechanism stresses caused by the forces imposed on it during these maneuvers are below the allowable stress.
