PASSENGER RESPONSE TO RANDOM VIBRATION IN TRANSPORTATION VEHICLES. LITERATURE REVIEW

Current interest in dynamics and vibration of ground transportation vehicles arises from the fact that excessive levels can lead to unsafe operation and give uncomfortable rides for passengers. The design of vehicle suspension systems and specification of roadway or guideway roughness levels hinge on the availability of ride quality criteria. Overdesign can lead to excessive cost. The report deals with a survey of available literature dealing with the effects of random vibration. The typical vehicle environment has broad-band characteristics. Some conclusions can be drawn. Firstly, passengers can distinguish between different levels of random vibration but coloration differences are hard to distinguish. Secondly, it appears, generally, that experimental research has involved relatively few subjects and the confidence level in criteria so far established is not high.
