The implication of random vibrations generated by rough route

The book presents a careful analysis realised of the vibratory phenomenon that occurs during vehicle journeys on rugged and hard-to-reach roads.During their operation, vehicles are subject to shocks and vibrations that come directly from internal sources and from external sources. The vibrations are a mechanical agent, with a toxic action on the military personnel and on the military equipment used by them during the missions.The unevenness of the driveway creates shocks on the wheel, these being converted to low frequency oscillations through the tire and through the suspension, being subsequently transmitted to the structural frame of the vehicle and hence to the seats. The discomfort is felt by people in the vehicle during displacements,when the level of oscillations transmitted by the vehicle's structure exceeds a certain spectrum frequency and amplitude. The reactions of the human body under vibrations are psycho-physiological reactions so that in addition to the structure of the individual.The reduction of the values product by these in order to improve the comfort is a very complex issue.
