Vibration and noise of a tracked forestry vehicle.
The vibration and noise of a modular rubber tracked forestry vehicle were examined.
The acceleration experienced at the driver's seat and the steering-wheel and the noise level at the driver's ear were measured under repeatable test conditions, on a bituminous conglomerate track, with different forward speeds and with the engine at maximum speed.
Measurements of vibration and noise were also carried out on a very uneven natural terrain to examine a condition of high risk from vibration transmitted to the driver.
The results of the study indicate that the level of vibration on the track test was low and should not compromise the health of the driver.
However, during transport on uneven ground and at high average speed (12 km/h), vibration at the seat (1.7 m/s2) was such that a driver's exposure, prudently, should not exceed 2 h per day, if the most stringent criterion of the International Standard is followed.
Noise levels were high, in all the test conditions [from 86 to 91 dB (A) ], as a result of the position of the engine in the cab and the lack of adequate soundproofing measures.
