dc.description.abstract The aim of the thesis is to compare results obtained from a finite element analysis method (FEM) to experimental results of an l2.2m long semi-trailer driven off-road. Semi-trailers are of great importance in the transport industry. Furthermore, the need to obtain optimum and reliable semi- trailers in this crucial stream of industry is indispensable. The work focuses on comparing the two results so that the finite element method may be used as design analysis and redesigning tool as a substitute to testing. The semi-trailer was driven on a relatively rough off-road at different speeds, at 70km/h, 50km/h and 40kmIh loaded with about 12 tonnes of brick pallets. The forces at the suspension of the semi-trailer and strains at different parts were measured with the help of strain gauges and other data acquisition equipment. A finite element model of the semi-trailer was modelled in Nastran for Windows. The trailer parameters in the finite element were tuned to curve fit the test results. A comparison of the two results was made based on the average of absolute values and standard deviation, to verify the validity of the finite element model. en
