Abstract: The cardan shaft transfers torsional loads from the gearbox to the rear axle for vehicle motion. The dynamics of the cardan shaft can be very complex because although one head of the shaft is fixed to the gearbox, the other end can move in the vertical plane when the vehicle is running on an uneven road. The cardan shaft is twisted and bent at different rotational speeds. When the torsional oscillation frequency of the cardan shaft coincides with one of its natural frequencies, it will induce resonance and therefore causing structural damage. The paper presents the analysis of the cardan shaft’s natural frequencies with two different materials, one using the conventional sheet metal and one using the composite material. The calculations can be used as the basis for designing the cardan shaft in the vehicle powertrain system of vehicles. The results of the study have shown the effectiveness of using composite materials for the cardan shafts in the automotive powertrain system. Based on this study, it is also suggested to use composite materials for some other shaft parts in the vehicle.

Keywords:Cardan shaft, Torsion vibration, Composite material
