Abstract
A method for testing the lumbar spine performance of a crash test dummy includes the following steps: selecting a lumbar spine performance test item; collecting data of at least one preset physical quantity during the collision process between the pendulum and the energy-absorbing buffer block through sensors on the lumbar spine assembly; determining whether the data of each preset physical quantity is within the corresponding data channel; if the data of each preset physical quantity is within the corresponding data channel, the lumbar spine assembly is deemed qualified for the current lumbar spine performance test item. This disclosure evaluates the quality of the lumbar spine performance of crash test dummies, allowing only those with better lumbar spine performance to participate in crash tests, and therefore improving the consistency and accuracy of different crash test dummies' response in crash tests.
