| 摘要： | Being assembled of many moving parts, every vehicle is a source of harmful noise. Total vehicle noise is a sum of noise contributions produced by parts that appear as noise sources. The most important noise sources seem to be the vehicle driveline system parts, i.e. engine, transmission, axles and tires. However, total noise indication by itself is not sufficient and detailed signal analysis is necessary to be performed so as to identify individual noise sources. This paper presents methods of measuring noise emitted by heavy off-road vehicles, which is used by Tatra Company in the early stage of truck development, in particular, external noise investigation and introduction of measures regarding noise emissions in production are mentioned. |
