Problems of vibration safety of operator of industrial tractor

Registration of dynamic processes in the context of real operation gave the researches opportunity to find the source of low-frequency vibration impact driven by rotation of caterpillar track in supporting frame of by-pass which is, according to biomedical researches, the most unfavorable for the body of the operator. The linear discrete model of the “Antivibration seat - Pelvis - Body - Head” system is studied as well as the impact of the dynamic parameters of antivibration seat on the level of vibrational load of the operator.
