This paper is a research that confirms the difference in the results according to the physical properties of the model when the head is made into impacted 3D human model. The structure of the head consists of skin, skull, dura mater, arachnoid layer, pia mater, and cerebral cortex. Currently 3D model is composed of skin layer, skull layer and Cerebrospinal fluid (CSF) layer. In this model CSF is layer that dura mater, arachnoid layer pia mater are combined into one layer. In this 3D model, the CSF layer model was compared with the fluid field and the Solid model, and the simulation results were compared. The fluid field analysis of the 3D model was performed using the Arbitrary Lagrangian Euler (ALE) method and the program was performed using LS-DYNA. Peak pressure data of the frontal, occipital, parietal, and fossa areas of the brain in the model and the various data values such as the total momentum and impact force of the model were analysised according to the change of the CSF layer. Ultimately, this model is designed to measure the mechanism of the brain damage and the whiplash injury. Therefore, it is the goal of this study to acquire accurate data consistent with the impact test and apply it to the 3D human model.
