This paper analyses the human body-machinery dynamic interaction in case of vibrating rollers used for road construction and maintenance works taking into account the nature and the character of the vibrations transmitted when both rollers are vibrating. Basing on the standard curves, the significant situations for the human body behaviour while the operator is subjected to various vibrating regimes are analysed aiming to characterise the possible effects concerning human safety and health. The paper will present results of the experimental measurements regarding the vibrations transmitted to human body in case of vibrating rollers provided with control station. Aiming a more detailed analysis for the vibration reduction modality the characteristic curves for the vibration transmitted from the vibrating roller to the machine cabin will be represented. Aiming to minimise the vibrations transmitted to human body the curves specific to the vibration transmission in case of the human body-machinery system can be used for the adoption of the engineering methods intended for evaluation of the dynamic model.
