Abstract
The Armored Personnel Carrier (APC) Brazilian military vehicle called APC URUTU EE-11 was developed in the 70s by ENGESA to fulfill the Brazilian army needs at the time. Nowadays, this vehicle's use has been redirected to civil police operations, where it takes personnel to urban areas of difficult access due to narrow streets, sharp turns and low adherence inclined pathways. Therefore, this work proposes replacing ENGESA's boomerang rear axle, a double wheel axle with dedicated gear boxes, with a single rear steering axle. The adaptation for an all wheel steering vehicle aims at reducing it's weight and making it more agile, once the unsprung vehicle mass is reduced and the rear wheel steering system increases it's maneuverability. Furthermore, a Matlab/Simulink simulation is conducted to compare the agility of both versions of the vehicle, testing their lateral dynamics performance in different speeds and curvature radii, through a bicycle model of each steering configuration. Finally, a conclusion is presented to address the viability of this adaptation.
