- Abstract
- National statistics on work safety are pointing out a decreasing trend
about related injuries and fatalities but an increasing number of reports
about professional diseases. In this frame are also considered the
mechanical vibrations, in particular whole-body vibrations (WBV). This
study aims to reproduce and analyse the vertical displacement of the
wheel of an agricultural tractor during the passage on a standard surface
(ISO 5008) for defining potential correlations between the surface contour
and the effects on vehicle dynamic and driver comfort by analysis of
the signals acting under the tractor tires. An agricultural tractor, in four
setting conditions and four different forward speeds, was tested on an ISO 5008 standard test track. The accelerations at the hubs of the tractor were
acquired and subsequently reproduced on a four hydraulic actuators test
bench, at CRA-ING laboratories, Treviglio, Italy. The analysis of the spectrums
generated have shown that a roughness surface induces a transformation
of the part of energy developed by the forward speed of the vehicle
in vertical acceleration that excites the elastic parts (i.e. tires, suspensions).
These phenomena seem to indicate that vehicle's vibration entity
is due to the combination of surface roughness and forward speed as
amplitude and to the elastic properties of the vehicle as frequency. (literal)
