A study to determine dynamic loadings affecting the semi-trailer frame

Abstract

This study aim is to develop and simulate dynamics of a combination
tractor and semi-trailer to determine dynamic loading generated at semitrailer chassis frame. Dynamics model of articulated vehicle with 40 feet
semi-trailer using Matlab/Simulink. Dynamic loading in motion generated
mostly due to the excitation from the rough surface of the road via wheels
and suspension system to the frame chassis. This model is usually utilized
to study the vibration problem (NVH) and structural strength analysis. The
results of analysing model are the dynamic loads generated when the
vehicle travels on road surface with the typical bump and road roughness
profiles in accordance with ISO 8608. The research results are plotted for
assessing and analyzing the applicability of the proposed model.
