摘要： A method for calibrating a chest of a vehicle crash dummy, includes: controlling, under each preset test condition, a pressing apparatus to press down a chest of a target crash dummy with a target pressing speed and a target pressing distance corresponding to the preset test condition, obtaining an actual force-displacement curve under each preset test condition, obtaining a standard force-displacement curve of a chest of a standard crash dummy under each preset test condition, and determining, according to the actual force-displacement curve and the standard force-displacement curve under each preset test condition, whether the chest of the target crash dummy satisfies a biological simulation standard. Through collecting information under various preset test conditions, various complicated conditions of impact on the chest can be more effectively simulated in a crash test by using the method, which improves the accuracy of determining the biological simulation standard.
