In the scope of the study, design, prototyping and the fatigue test phases of a double wishbone independent suspension that is designed for the front axles of the articulated heavy commercial vehicles were carried out. For this reason, firstly, optimal suspension geometry which satisfies the minimum camber angle and track change targets during the wheel travel was obtained with the use of multibody dynamics and response surface methodology by taking the design constraints of the front axle of the model vehicle. Forces acting on the hardpoints of the system during the service were determined by using the standard driving manoeuvres which were applied to a full articulated vehicle model. By using these forces, pre-mechanical design of the system was carried out. Finite element analyses were applied to this design model by using the standard load cases given in the literature. Design improvements were applied to the critical stress concentrated regions which were determined on this model. Full scaled prototypes of the completed system were manufactured. Fatigue analyses were also applied to these prototypes with the use of the real load data. No overload or fatigue-based failure was observed during the tests.
