VIBRATION STRESS OF DRIVERS IN COMMERCIAL VEHICLES

SCHWINGBEANSPRUNCHUNG VON FAHRERN IN NUTZKRAFTWAGEN

After a brief description of the effect of mechanical vibrations on the human body, vehicle vibrations are discussed, with particular reference to vibration stress on drivers. Studies have shown that, given an optimum seat height adjustment, on average 16.8 percent plus or minus 2.86 percent of the body mass above the feet is supported. For the rigid seat studied the supported proportion of the body mass amount to 20.53 percent plus or minus 2.73 percent. Measurements of a driver on a bad asphalt road at a speed of 60 km/h show that the dispersions in total body vibrations and thus the transfer mass for both seats are normally distributed. The relative dispersions in the seat accelerations are about two to four times greater on the centrally sprung seat than on the rigid seat. Because of the effects of road condition, speed, transmission behaviour of the vehicle oscillation system and the driver, a comparative study of different vehicles should be carried out under repeatable test conditions. Optimum vibration comfort can only be achieved if the driver-seat system can be adapted to the anthropometric data of the driver. (TRRL)
