Research of Noise, Vibration and Harshness of vehicles (Vehicle NVH) has been the focus of the department’s activity for quite long. The members of the team have many years of experience in the development of research methods, measurement set up and realization of research in this area. This field is very interesting for the automotive industry, but developed research methods in the area of oscillatory and acoustic comfort of vehicles are applied in other fields too, as well as in solving the environmental protection issues due to unwanted effects of the traffic noise.
Activities:
• Investigations of dynamics of vehicle’s elements and structures
• Testing of the vehicles comfort
• Development of research and analysis methods
• Development of data analysis program
• Identification of regulation-technical characteristics of a driver
• Development of identification methods
• Design of measuring and testing equipment
• Measuring of internal and external vehicle noise, as well as noise in driver`s working places, public places, traffic roads, etc.
• Measuring of vibration and oscillatory comfort
• Analysis of noise and vibration
• Software development
