Predicting the transmissibility of a suspension seat

Abstract

Measurements of the stiffness and the damping of an air suspension seat were made. The seat was loaded with either a person or an equivalent rigid mass, and the effect of the following variables was investigated: duration; vibration magnitude; load on-the seat; seat adjustment. The results obtained with a rigid mass were used in conjunction with previous measurements of the apparent mass of the body and the apparent mass of the legs, to predict the transmissibility of the seat with a person. Good agreement was obtained between measured and predicted seat transmissibilities.
