THE APPLICATION OF STRESS, NOISE AND VIBRATION ANALYSIS TO DESIGN OF RAIL RAPID TRANSIT VEHICLES

This is a review paper dealing with design developments occurring with the aid of, or as a result of, noise and vibration analysis. To examine the main strength of A vehicle body, finite element techniques now provide a method vastly superior to previous methods, but its cost and complexity cannot always be justified at the present time. The much simpler framework analysis and approximate methods still have important functions. Comprehensive structural testing employing strain measurement techniques provides not only a final check on a new design but also yields information invaluable in the evolution of later designs. These techniques are applied to produce designs lighter in weight, cheaper in material or manufacturing costs, and hence more economic to the operator, whilst at the same time preserving the reliability and freedom from fatigue required for a vehicle life of 30 years or more. Increasing public awareness of noise being a form of environmental pollution is leading to greater efforts to produce quieter vehicles, both from the passenger's point of view and with regard to wayside problems. Measurement and analysis techniques show that great improvements can be achieved, often without undue penalities in cost and weight. Attention is given to vibration isolation of the body from track irregularities, rotating machines on the body and to the effect of the body itself as a vibrating beam. (a).
