613 - Isolation of vibrations transmitted to the operator of vibrating rollers used for compacting works
Bratu P.
Abstract
This paper presents in a synthetic manner the research results obtained by the author concerning the dynamic modelling of the vibrating rollers. Thus, the theoretical approach as well as the experimental results for a class of vibrating rollers having the mass in the range 4 000 kg … 10 000 kg and maximum perturbing forces between 20 kN and 120 kN for harmonic vibration working frequencies in the interval 25 Hz … 60 Hz are presented. The results obtained for a compacting roller having two isolation stages as compared with the existing solution where the machines are provided with a single isolation stage. Also, there will be analysed the cases of vibration isolation degree variation when the rigidity of the first isolation stage changes, by discrete values technically feasible. Finally, the results of the effective tests in case of machines in the mentioned category of vibrating rollers, including the variation curves of the vibration transmissibility having impact upon the operator in the machine cabin are presented and analysed.
