          Abstract

          A synthetic test method is described which is capable of investigating various suspension fasteners on a dynamic half-axle test rig. This test method is advantageous compared to an expensive and time-consuming driving cycle. In advance vehicle specific measured values that serve as input parameters for the test rig experiments are required. This study shows how the adhesion limit influences the interdependencies between vertical load, side slip angle and longitudinal slip. By means of multibody systems and in consideration of the determined nonlinear tire characteristics, this method can be applied to investigate suspension fasteners of vehicles without expensive and time-consuming test drives. Validation results of different vehicles are given which demonstrate that the method is appropriate to a wide range of vehicles.

          Kurzfassung

          Zur Variantenuntersuchung von Fahrwerksverschraubungen auf einem dynamischen Halbachsprüfstand ist eine synthetische Prüfmethode entwickelt worden, um eine Alternative zum realen Fahrversuch zu schaffen. Für die Methode sind fahrzeugspezifische Größen erforderlich, welche als Eingangsgrößen für den Prüfstandversuch genutzt werden. Mit Hilfe einer MKS-Simulation des Fahrzeuges und unter Beachtung der ermittelten nicht linearen Reifeneigenschaften kann die Methode bereits im Vorserienstand zur Untersuchung von Fahrwerksverschraubungen auf einem hoch dynamischen Rundkursmanöver angewendet werden. Darüber hinaus liegen Validierungsergebnisse verschiedener Fahrzeugtypen vor, welche die Anwendbarkeit der Methode auf ein großes Fahrzeugspektrum aufzeigen.
