内容記述 | A driver feels discrepancy between the actual measured aerodynamic noise generated from an automobile door mirror and own impression. In order to clarify the mechanism of the gap on the sense of the noise, we estimated quantitatively the influence of assembly quality of the door mirror on the aerodynamic noise in the wind tunnel experiment. The aerodynamic noise of the door mirror is analyzed based on Curle’s equation using the characteristics of the wake structure. The clearance between the panel of the body and base of the door mirror affects the noise level in the high frequency domain, whereas the clearance between the base and visor influences the noise level in the low frequency domain. We analyzed the mechanism of the aerodynamic noise as the noise level becomes large due to the increase of the wake width when the clearance between the base and visor is increased. |
