Abstract: For a moving car, buffeting noise is generated when a window is opened alone, which seriously affects the comfort of passengers. In particular, there is still no effective control method for side window buffeting, so it is very important to study the buffeting mechanism and characteristics for noise control. First, this paper analyses the pressure change law during the shear vortex shedding process through simulation, and explores the Helmholtz resonance characteristics of the passenger cabin, so as to reveal the causes of buffeting phenomenon. Secondly, wind tunnel tests are used to study the effects of vehicle speed, window opening size and other factors on buffeting, and the differences in buffeting characteristics between sunroof and side windows are compared, then the reasons for buffeting changes are analysed through simulation. Finally, the passive control and active control are discussed, which have reference significance for the control of vehicle window buffeting.
