The Apparent Mass of the Seated Human Body in Response to Lateral and Roll Vibration
The objective of this study was to compare the lateral apparent mass of the seated human body measured in response to lateral and roll motions. The lateral apparent mass was measured at the seat surface using a rigid flat seat with no backrest. The axis of rotation of the roll motions was also at the seat surface. Tests were conducted using pseudo-random motions band-limited at 0.2 and 2 Hz rep...
متن کاملResponse of the seated human body to whole-body vertical vibration: biodynamic responses to mechanical shocks.
The biodynamic response of the seated human body has been investigated with 20 males exposed to upward and downward shocks at 13 fundamental frequencies (1-16 Hz) and 18 magnitudes (up to ±8.3 ms-2). For 1- and 2- degree-of-freedom models, the stiffness and damping coefficients were obtained by fitting seat acceleration waveforms predicted from the measured force to the measured seat accelerati...
متن کاملControl of Electric Wheelchair Suspension System based on Biodynamic Response of Seated Human Body
Electric wheelchair is one of the equipment to be used by the incapacitated and disable people. Constant exposure to vibration affects human comfort and health. Reducing the vibrations transmitted to the human body is important in the electric wheelchair design and becomes a healthcare industry demand. This paper deals with the study on vibration control of the electric wheelchair suspension sy...
متن کاملBiodynamic response of the seated human body to single-axis and dual-axis vibration: effect of backrest and non-linearity.
The biodynamic responses to the human body give an understanding of why human responses to vibration (changes in health, comfort, and performance) vary with the frequency and direction of vibration. Studies have shown that biodynamic responses also vary with the magnitude of vibration and that the backrests of seats influence the transmission of vibration to the seated human body. There has bee...
متن کاملExploring Biodynamic Response (Apparent Masses) of a Seated Human Body Exposed To External Excitation in Vertical Direction
In the present work, the biodynamic response behavior of seated human body subject to vibration in vertical direction have been extensively examined. The biodynamic response parameter of seated human body have been analyzed in terms of apparent masss (AM).The AM describe “to –the -body”force motion relationship at the interface of huma and seat. The present work proposed the six degrees of free...
