Detailed Description
Referring to fig. 1 to 3, the wind vibration eliminating system for a vehicle according to the embodiment of the present invention is mainly composed of a rear quarter window structure 10, a driving device 30, and a control device 40. Therein, the rear quarter window structure 10 may be installed at a rear window position of the vehicle, and adjacent to the rear side window glass 21, the rear windshield glass 22 and the C-pillar 23. The rear window structure 10 has an opening 13 that can be opened or closed, and the rear window structure 10 is configured to open or close the opening 13 of the rear window structure 10 in a controlled manner according to the opening degree of the opened window and the speed of the vehicle, so as to eliminate wind vibration, avoid irreversible hearing damage to the user, and improve the comfort of the user.
The window opening wind vibration rolling generation principle of the passenger car is as follows: referring to FIG. 4, when a user is in a high speed windowing condition (e.g., 40-100km/h condition), the tangential flow of the leading edge of the vehicle window drops off due to the lack of a surface to which it continues to adhere, creating a vortex. The vortex moves further rearward and expands, impacting the cavity in the vehicle and the rear edge of the window. The inner cavity of the vehicle is impacted by vortex, and regular expansion and contraction (short for pressure fluctuation) of 10-20Hz occurs because the pressure cannot be released in time. The vortices impacting the window trailing edge are reflected by the trailing edge wall (vortex reflection), creating a positive excitation to the leading vortex, further exacerbating the vortex shedding by the window leading edge. Just because of the violent impact and extrusion of the vortex on the cavity in the vehicle, the cavity resonates at corresponding frequencies, the resonant frequencies are generally distributed between 10 and 20Hz, and the amplitude is generally more than 120dB (see figure 7). When the human ear is exposed to an environment of more than 110dB for a long time, irreversible hearing damage, such as perforation of eardrum, leakage of ear tissue fluid, tinnitus, ear pain, etc., may be caused.
