INFLUENTIAL FACTORS ON THE RESPONSE OF A BODY EXPOSED TO MULTIAXIAL VIBRATIONS

Abstract

Whole-body vibrations represent one of the causes of spinal disorders in humans. Prolonged exposure to multiaxial vibrations can lead to harmful consequences for the musculoskeletal system, while repetitive occurrences may result in the development of pathological changes in the spinal column. The biodynamic responses of seated passengers exposed to whole-body vibrations have been extensively studied in terms of the apparent mass or seat-head transfer functions across a wide frequency range of vibrations. In this work, the subjects were exposed to multiaxial vibrations. Seat-head transfer functions were determined in order to evaluate the biodynamic response of the body and influencing factors on the frequency response.
