Optimization of vibraiton comfort of heavy duty trucks

In this thesis, a model based approach have been applied in order to provide a better and compact design for heavy duty trucks? cabin suspensions. A 7 DOF half truck model was built in Matlab/Simulink and a multi DOF model was built in Solidworks and Matlab/Simmechanics. For the time and frequency domain the results are evaluated accoring to ISO 2631-1 standard. Then the design options have been plotted in graphics in order to provide a compact choice of solution for cabin suspension design. The differences in the results of two simulations have been observed and the reasons are discussed. A user friendly guide user interface has been developed in order to obtain quick results and easy parameter selection. After the simulations a significant performance improvement in the ride comfort has been obtained.
