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.

摘要： Disclosed are a tool and a method for measuring a parallelism and an angle of a shank skeleton of a vehicle crash dummy. The tool includes: a fixation seat, where a magnetic fastener is arranged on the fixation seat and configured to mount a shank U-shaped member; and a movement assembly that is configured to drive a measurement assembly to move, so as to change a relative position of a measurement end of the measurement assembly and the shank U-shaped member. The condition that the measurement assembly directly comes into contact with the shank U-shaped member, and damages a surface of the shank U-shaped member is avoided while making an entire measurement process more convenient.
