MODELING OF TRACTOR SEAT WITH REDUCED RISK OF WHOLE BODY VIBRATION

Exposure to vibration is the cause of some occupational injuries and diseases. The objective of this study was determination of transmission of vibration which transmitted to tractor drivers from the seat operator system and breaking system. An investigation was conducted to determine the transmission of vibration from the seat operator system & breaking system to the neck, low back & feet under the different conditions i.e., farm field, tar - macadam road & bricks road. The vibration level was measured and analyzed and the frequency spectra for the chosen working conditions were obtained. The results indicate that the maximum transmissibility was observed in the first two frequency interval (in Hz) i.e. 1 - 5 and 6 - 10. PRACTITIONER SUMMARY: The study of this paper is analysis of vibration in tractor driving that can causes deafness and disorders of the spinal column and stomach. The effect of implements on tractor ride is not well understood in India
