SHAFT VIBRATION OF THE TRUCK

Abstract eng:
This article describes analysis of vibrations in a powertrain of a truck with 8 x 8 drive. It may be caused by a deflection of the rotating drive shaft. The aim was to reduce the vibrations, therefore, a transient computational model I for analysis of shaft deflection was created in Matlab software. Analytical and differential equations are used. This model I was compared to the simulation of the transient behaviour of model II with the use of FEM. To verify the computational models, measurements of the shaft deflection and directional vibrations were carried out. The conclusion presents the interpretation of the results of old and new modification of the powertrain and the cause of vibration is also demonstrated.
