The aim of the work reported here is to consider the vibration experienced by a tractor driver. The tractor seat is assumed to be equipped with a semi-active suspension having an MR fluid damper. Based on experimental data, a parametric model for the MR damper behaviour is obtained and the r.m.s. body acceleration response to an Measured seat base random displacement is determined by numerical simulation for both optimum semi-active and passive suspensions. The following conclusions were obtained: The semi-active seat suspension with controllable MR fluid damper, can satisfactorily reduce the accelerations experienced by the tractor driver. By using either crisp or fuzzy control strategies based on balance logic a reduction of about 40 % compared to the optimum passive suspension is predicted. By using a semi-active seat suspension with MR damper controlled by balance logic strategy, the acceleration frequency response of the driver body can be significantly reduced over the entire frequency range of practical interest. This is not possible for passive suspensions with either linear or non-linear damping characteristics.
