Laboratory studies data

Experimental studies are being performed to extend current knowledge of the fundamental relationships between low-frequency motions, discomfort and interference with activities of passengers and crew. Discomfort caused by low frequency motion is particularly important because it can occur even when other effects are not present (e.g. there is no interference with activities or motion sickness) and because there is currently very little knowledge of how to predict discomfort caused by low frequency translational and rotational motions such as may occur on fast vessels.

The specific aims are to investigate the response of seated and standing persons to motions in four axes: ry (pitch), x-axis (fore-and-aft), rx (roll) and y-axis (lateral). These studies encompass motions at frequencies between 0.2Hz and 1.6Hz, and include consideration of the influence of postural support, especially backrest support. The results will be used to allow comparison of absolute levels of discomfort between ry (pitch) and x-axis (fore-and-aft) response, and between rx (roll) and y-axis (lateral) response, and to provide information for extending the frequency weightings used in current methods for evaluating ride comfort so as to encompass low-frequency ship motions.
