The article deals with the creation of a transient computational model of rotating shaft deflection. This model is used for analysis of vibrations in the truck powertrain with an 8x8 drive. This vehicle is intended for military or fire purposes. However, issues with powertrain vibrations after reaching a certain vehicle speed appear. It was assumed that it was caused by the revolutions of the powertrain shaft and its deflection. Therefore, the aim is to reduce the vibrations affecting the drive comfort and prepare a computational model of the shaft. The transient computational model was created in Matlab software and compared with the results of a second model with the use of the finite element method. The second computational model works as a control version for the first model. The verification was carried out with the use of measurement of shaft deflection and directional vibrations on the powertrain. The conclusion shows the results of the comparison between the old and the new version of powertrain where vibrations were reduced.
