This master thesis addresses the dimensioning of a hydraulic suspension system for a hybrid forest truck (HFT) under development. Furthermore, the suspension system has been modelled in MATLAB/Simulink and an environment has been set-up for a cosimulation with the vehicle model in MSC Adams. The interface between the programs has been determined and the required preprocess is described, step by step. Numerical problems and challenges that have arisen have been discussed, together with recommendations for how they could be solved. The purpose of the co-simulations have been to analyse the vehicle vibration levels and tune component parameters, such that, the international standard for whole-body vibrations, ISO 2631-1 (1997) and AFS 2005:15 (2005) can be met. The results are presented and clearly shows that the vibration levels in the vehicle cab are acceptable according to the standards. Moreover, recommendations are given for future work regarding how cosimulation problems could be solved, but also how to develop this passive suspension system to be of active type.
