Growing awareness that uncomfortable agricultural vehicles endanger the health of the operators and stricter norms concerning this, make the design of an effective cabin suspension inevitable on agricultural vehicles. The comfort problem originates from the vibrations transmitted to the driver caused by the unevenness of the road or soil profile. The effect of a passive and semi-active cabin suspension on the comfort of the drivers is investigated. . The optimization of the suspension is based on the frequency response function of the system. By optimizing the parameters of the passive suspension and those of the semi-active control laws, satisfactory improvement of the comfort can be achieved. The results shown prove that an improvement of comfort resulting in a reduction of comfort values by more than 60 % are possible using an optimized passive suspension system. With a small additional investment it is possible to reduce the levels a great deal more (up to 90%).
