Automatic test device for simulating sudden damage of door and window in wind tunnel test

The invention discloses an automatic test device for simulating sudden damage of a door and window in a wind tunnel test. The automatic test device comprises a first elastic piece and a first unhooking mechanism which are arranged on the inner side of the test door and window, and a second elastic piece and a second unhooking mechanism which are arranged on the outer side of the test door and window. The wind pressure sensor is used for acquiring the wind pressure difference between the inner and outer sides of the test door and window; the control unit is used for releasing the connection between the first unhooking mechanism and the first elastic piece and unlocking the electromagnetic lock when the inner side wind pressure of the test door and window is greater than the outer side wind pressure and the wind pressure difference exceeds a threshold value; and when the inner side wind pressure of the test door and window is smaller than the outer side wind pressure and the wind pressure difference exceeds a t
