Course detail
Vibration and Noise of Vehicles
FSI-QDZ-AAcad. year: 2020/2021
In the course, the physical fundamentals of the vibrations and noise sources and propagation are presented. The course introduces analytical and numerical methods of vibration and noise description including experimental methods with subsequent application of these methods to selected problems of motor vehicles. Emphasis is placed on understanding the physical nature of vibrations and noise with subsequent measures to reduce negative effects. The issue is applied to selected cases occurring in technical practice, such as vehicles, powertrains or their components.
