Wind-Induced Vibration of the Rear-View Mirrors of Car at High Speed

Abstract

Rear-view mirrors vibration that was dangerous when the car is moving at high speed poses a serious threat to traffic safety. The wind-induced vibration has been one of the urgent issues in rear-view mirror system. The air power generated when the car is fast moving and inertia force generated when the rear-view mirror vibrates, constitute a feedback process in the form of a closed loop, so that the amplitude will increase with time. A gas excitation model coupled rearview mirror with air flow vibration was established. CAE analysis method was adopted to prove the theoretical methods.
