SZWEDOWICZ, Dariusz et al. Numerical model of a head-neck dummy for crash tests. Rev. cienc. tecnol. [online]. 2023, vol.6, n.2, e249.  Epub Aug 14, 2023. ISSN 2594-1925.  https://doi.org/10.37636/recit.v6n2e249.

When car crashes occur, the impact energy is transferred to passengers, provoking fatalities, and severe injuries. In this sense, the use of dummies to analyze the effect of dynamic loads on the human body is increasing. However, its cost is generally expensive and difficult to acquire. Thus, the current article proposes designing and developing a head-neck dummy using Abaqus finite element method software. The design of the dummy model is formed by the head, and neck which are formed by cervical and intervertebral plates. The assessment of the new head-neck model was carried out by a pendulum test. During the evaluation of parameters such as acceleration, velocity force, and angular position of the head were obtained. Finally, the results of the viability of the model were validated through the whiplash phenomenon.
