dcterms:description
The work deals with the simulation of the motorcycle helmet drop test with the numerical software LS-Dyna. The aim of study was to obtain acceleration values of the headform gravity center. The factors of head injuries HIC were determined from the acceleration values. The model of motorcycle helmets was created by using of a 3D handheld scanner. An impact pad was created and the headform model was modified. The draft for the model was represented by a real motorcycle helmet. Properties of materials used for making the actual helmet were assigned to the motorcycle helmet model. The quality of helmets is assessed in terms of damping properties at the drop test. Damping properties were assessed on the basis of the acceleration values of the head gravity center. A drop test was also performed on the pads rotated in different directions. The problems of motorcycle helmets testing in Europe is adjusted by the ECE 22-05 standard. The standard primarily determines how to make drop tests.
