Kinematic and dynamic analysis of a heavy truck with individual front suspension

Journal article, 2013

The main focus of this work is on the characteristics of a commercial vehicle with Individual Front Suspension (IFS). Both kinematic and dynamic properties of the vehicle are investigated through simulations and analytical expressions. Moreover, employing the model of the tractor semitrailer combination, the study presents the results of comparison between the trucks with IFS and rigid front axle with respect to comfort and handling. This is done by analyzing the responses of the vehicles to different road and steering inputs. The obtained results show enhanced comfort and steering feeling for the truck with IFS.
