Rearview mirror inherent frequency test method

The invention relates to the technical field of automobile rearview mirrors, and discloses a rearview mirror inherent frequency test method, which comprises the following steps of: installing a rearview mirror on a three-comprehensive vibration test bench, and generating an inherent frequency conclusion curve; the device is installed on a real vehicle to test the inherent frequency of the real vehicle, and a frequency value needing to be adjusted of the rearview mirror is obtained. The device is installed on a three-comprehensive vibration test bench, a vibration optical performance test is adopted to record the frequency value with the maximum amplitude, and the rearview mirror is subjected to physical improvement according to the frequency value needing to be adjusted of the rearview mirror and the inherent frequency conclusion curve. And the rearview mirror which is effectively improved in a real object is installed on a real vehicle, and final verification is completed. According to the method for testing
