Impedance methods (apparent mass, driving point mechanical impedance and absorbed power) for assessment of the biomechanical response of the seated person to whole-body vibration.
Exposure to whole-body vibration is a risk factor for the development of low back pain. In order to develop a fuller understanding of the response of the seated person to vibration, experiments have been conducted in the laboratory investigating the biomechanics of the seated person. Some of these methods are based on the driving force and acceleration at the seat and are reported in the litera...
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 کاملThe 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: discomfort caused by mechanical shocks.
The frequency dependence of discomfort caused by vertical mechanical shocks has been investigated with 20 seated males exposed to upward and downward shocks at 13 fundamental frequencies (1-16 Hz) and 18 magnitudes (±0.12 to ±8.3 ms-2). The rate of growth of discomfort with increasing shock magnitude depended on the fundamental frequency of the shocks, so the frequency dependence of equivalent ...
