Minimization of Tractor-Occupant's Traumatic Vibrational Response by Means of the “Patil-Palanichamy-Ghista” (PPG) Tractor Seat Suspension

DOI: 10.1016/s0166-1116(09)70163-3


Summary It is shown that a newly developed (“PPG”) tractor seat suspension system drastically improves the tolerance to high intensity vibrations in the 0.5-11 Hz range experienced by tractor occupants, by reducing (i) the maximum amplitude ratios and relative displacements of the body parts to 0.0076 and 0.12 mm respectively, and (ii) the body parts' acceleration to levels much below the ISO specified discomfort limit.
