A Study to Investigate Vibration Exposure among Tractor Drivers - Chander Prakash - Bog

The occupational ride comfort response among tractor drivers due to the exposure of whole body vibration are explored under the three most commonly used sitting postures i.e. lean forward, vertical erect with no backrest, leaning with backrest. The whole body vibration levels are measured on two terrains: on-road (tractor with no attachment) and off-road (harrowing task) in terms of weighted root mean squared acceleration, daily exposure, vibration dose values and daily dose values. The frequency response with respect to performed activities is studied by using 1/3rd Octave Band Analysis.
