Abstract: Steering wheel vibration affects the driver's comfort in an agricultural tractor. In order to increase driver comfort and reduce the hand-arm vibration syndrome (HAVS) effect, it is necessary to reduce the vibrations in agricultural tractors. The tuned mass damper concept is used to reduce vibrations from the tractor's steering wheel. The paper is focused on measuring steering wheel vibration characteristics on the actual tractor, designing a vibration control system and carrying out impact assessment using numerical analysis. The amplitude of vibration at the steering wheel measured by physical measurement on an actual tractor is compared to that determined using MATLAB Simulink. The outcomes of the numerical analysis suggest that the amplitude of vibration can be reduced by using a tuned mass damper (TMD) to achieve the proposed target levels. The effect of hand-arm vibration syndrome can also be decreased, resulting in an increased driver comfort.
