Evaluation of Whole-Body Vibrations Effect on Tractor Driver in Indian Agricultural Conditions Using 4-Layered CAD Model

A tractor driver suffers from any ill effects due to whole-body vibrations that generate while performing operations in the agricultural field. The acceleration and the level of vibration amplitude vary as per the type of operation selected by the driver while cultivating the field. Even, the impact of vibrations varies according to the suspension type of tractor, field soil, weight, posture, and height of human subject along with other external conditions. The effect of whole-body vibrations on the Indian human subject with a mass of 76 kg equivalent to 95th percentile data of the human male population belonging to the Indian region was investigated in this study. During the disc harrowing process, three RPMs were considered: 1500, 2000, and 2500, with accelerations of 0.5 m/s 2 , 1 m/s 2 , and 1.5 m/s 2 . For finite element analysis, a CAD model (4-layered) consisting of skin, muscles, sensitive organs, and bones i.e. was employed.
