Biodynamic responses of the seated human body to single-axis and dual-axis vibration

Significance of output:

Studies of biodynamic responses of the seated human body to whole-body vibration have mostly investigated responses to single-axis excitation, especially vertical vibration. This paper is one of only a very few studies to have investigated the apparent masses of the seated human body without backrest during dual-axis fore-and-aft and vertical excitation. It is the only paper to have systematically explored the non-linearity of the body with dual-axis vibration and how this depends on the magnitude of vibration in each axis. The study provided necessary data required for biodynamic modelling and the findings are being used to optimise the seat design and ride dynamics by vehicle and seat manufacturers.
