Analyses of truck powertrain torque and vibration

Abstract

The article deals with an analysis of the mean value of the torque of the truck with 8x8 drive. Torque was measured using a noncontact device on the powertrain shaft. This shaft is used to drive the first front axle. For a better understanding of the experiment results, computational model of the truck was developed in Simulink software. To build the computational model, custom library was used and users could create different modifications of vehicles. Subsequently, analysis of torsional vibration was carried out. In the first study, the truck showed problems with directional vibrations and noise after reaching a certain speed, therefore, this article also continues with an analysis of the torsional vibration.vThe article deals with an analysis of the mean value of the torque of the truck with 8x8 drive.
