The methods of the NVH analysis in the field of railway vehicles
The main purpose of the NVH analysis (noise, vibration and harshness) in the railway engineering is to study and measure harmful effect of railway vehicle operation. The NVH allows to identify a source of a sound as well as the cause of its origin. The task for engineers of railway vehicles is to reduce or eliminate unwanted noises and other negative effects of vibration and noise. This article is focused on an overview of the known researches outputs related with the NVH analysis in railway vehicle. It also presents the possibilities to perform NVH analyses in a commercial simulation software. Further, the article contains a presentation of the most known and the most widely used methods for analysis of the noise, vibration and harshness (NVH) in the field of railway vehicle.
