Influence of the Fifth-Wheel Location and stiffness on the Tractors Semi-Trailers Handling and Ride
The coupling of a fifth-wheel on the tractor to a kingpin on the semi-trailer is an adopted joint mechanism, which is the only device for connecting the tractor and semitrailer, it is necessary for the kingpin and fifth-wheel to meet various requirements such as dynamic handling and ride performance by optimal location and stiffness. A tractor semitrailer multi-body model which considers non-linear vehicle dynamics, tyre models and suspension kinematic effects for both ride and handling simulations are presented. A select set of tests was performed to validate the predictive capabilities of the model. An investigation of the vertical dynamics of the tractor semi-trailer traversing a random road profile was conducted by sensitivity analysis with location and stiffness of the fifth-wheel. On the other hand, the violent lane change maneuver is investigated by sensitivity analysis with location and stiffness of the fifth-wheel. In addition, a new optimal law is proposed in order to minimize roll responses of both tractor and semi-trailer under the constraints by the ride index of the tractor.
