LABORATORY SIMULATION OF VIBRATORY ROAD SURFACE INPUTS

Much of the research activity so far reported in the area of human response to vibration relates to laboratory investigations based upon sinusoidal vibrations, which are easily generated and are deterministic in nature. Although such techniques have provided some useful information, sinusoidal excitations rarely occur in real life vibration problems and consequently results obtained may not be realistic. Most practical vibration problems involve random motions such as many be generated by a road vehicle wheel passing over a terrain. Very little is known of the effects of these random motions on human health, safety, comfort and performance. The object of this paper is to describe a new technique that has been developed at the University of Birmingham for simulating road surface inputs in the laboratory. It is hoped that the technique will be applicable to a number of problem areas in the field of human response to transportation vibration with particular reference to on-road vehicles.
