摘要： A method for scaling a vehicle crash dummy model, includes: obtaining a height ratio, a girth ratio, and a mass ratio of each part of a body shape of a target population to a reference population; calculating part scaling ratios of the target population to the reference population in a height direction and each direction in a girth plane according to the height ratio, the girth ratio, and the mass ratio; scaling simulation models of each part of a dummy simulation model of the reference population according to each scaling ratio; and assembling scaled models of each part, to obtain a dummy simulation model of the target population. This embodiment improves a shape simulation degree for a real human body of a dummy.

摘要： A method for measuring a relationship between crash dummy chest compression and a safety belt load, includes: controlling, when a dummy is fixed in a preset posture on a fixed bed in a test platform via a safety belt in a safety belt restraint apparatus, a chest cover plate in the test platform to move so as to maintain a preset relative position between the chest cover plate and the dummy; controlling an impact apparatus to pull the safety belt in each pulling force to be measured, and determining a target displacement value of each measuring point on the dummy and a target pulling force between the impact apparatus and the safety belt after a first preset duration; and determining a target pulling force-displacement curve corresponding to each measuring point according to each target displacement value and each target pulling force.

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.
