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.
