The invention relates to an automobile crash test dummy chest calibration device, which comprises a support, an impact hammer connected onto the support through a connecting rope, and a lifting mechanism which is used for lifting the impact hammer to a required height and is in split-connection with the impact hammer. The calibration device also comprises a test bed for mounting a dummy. The calibration device further comprises a display device for real-time display of the height of the impact hammer. According to the invention, the calibration device can display the height of the impact hammer in real time, and is simpler in operation, higher in accuracy and more precise in calibration test as compared with the prior art in which an operator measures the height of the impact hammer with a measuring gauge.
