Noise, Vibration and Harshness (NHV) Criteria as Functions of Vehicle Design and Consumer Expectations

摘要

The criteria for NVH design are to a large degree determined by the types of vehicles and thernperceived desires of the purchasers of vehicles, as well as the cost of incorporating NVHrnmeasures. Vehicles may be classified into specific types, e.g. economy car, mid-size passenger,rnnear-luxury and luxury passenger cars, sports cars, vans, minivans, and sports utility vehicles ofrnvarying sizes. The owner of a luxury sedan would expect a quiet ride with minimal vibration andrnharshness---however if that sedan is to display sporting characteristics, some aspects of NVHrnmay actually have to be increased in order to enhance a feeling of driver exhilaration. Arndiscussion of the requirements for specific types of vehicles is provided, with due regard forrneffects on the usability of installed sound/video systems, driver and passenger fatigue, feel ofrnsteering mechanisms and other mechanical components, consumer market research, etc. Arnnumber of examples of vehicles on the market are cited.
