Existing anthropometric test device heads use a rigid body structure. Therefore, the objective of this study was to model a new anthropometric test device head incorporating skull‐brain structure, conduct sled tests for investigating the head’s usability, evaluate the head’s performance at measuring brain‐skull relative motion. The new anthropometric test device head was constructed based on geometry obtained from an adult human male medical image. Sled tests corresponding to frontal crashes with the new anthropometric test device head mounted on a AM50 Hybrid III dummy were carried out. Moreover, a finite element model of the human head was developed and validated against post‐mortem human subject experiments, and the was validated from the results of corresponding brain node motion obtained from sled tests simulations. Although the brain node motion of the ATD head correlated with the simulation model, the maximum displacement of the ATD head were significantly larger than the human head FE model. Therefore, the novel ATD head showed a potential as a first concept of a new ATD head incorporating skull and brain structures which is capable of direct measurement and visualisation of intracranial brain motion, however, the biofidelity is needed to be improved.
