R. I. Rakhmatov, V. E. Krutolapov

Abstract

The article presents a calculation method of Noise-Vibration-Harshness (NVH) analysis of a vehicle, the purpose of which is to reduce noise pollution. The results of calculations and experimental validations of calculations, natural frequencies and oscillation modes of the trimmed body internal volume, local dynamic stiffnesses and frequency response are provided. Also, contribution of the body panels to forming internal noise is defined.
