Protective helmet behavior under dynamic load

Original language description

The article deals with the analysis of the foam part of the protective helmet under dynamic load. Protective helmets are tested by drop tests to meet technical standards. During them, the helmet is subjected to impact by a heavy rigid punch while being mounted on the head model. The standards specify the minimum value of energy that a helmet must absorb, while not exceeding the maximum permissible force transferred to the helmet user’s head. For possibility to improve these helmet properties by changing its geometry, a drop test simulation model is being created. The result of the drop test simulation of the helmet foam part is then compared with the measured stiffness characteristics.
