Abstract :
The numerical calculation and analysis for the coupling of vibration and interior sound field of a resistance cab has been carried out by using the FEM and the acoustic analysis software. This paper introduces the specific steps of the method of vibration´s modal analysis and the method of harmonic response analysis. Through calculation and analysis, get wainscot thickness which has the influence of vibration noise excavator cab, so as to find the biggest part of vibration, the parts of the improved structure, and finally reach the effect of noise.
