A motorcycle helmet is the best protective head gear for the prevention of head injuries caused by different carnial impact. A finite element model based on realistic geometric features of a motorcycle helmet is established, and explicit finite element, COSMOS, is employed to simulate dynamic responses at different impact velocities. Peak acceleration and Head Injury Criterion values derived from the head form are used to assess the protective performance of the helmet. In this present work

... r cycle helmet is designed and modelled in 3D modelling software Pro/Engineer. The impact analysis is performed on the helmet when colliding to a target at different speeds of 50 Km/hr, 60 Km/hr and 70 km/hr that faces the helmet on the front, right and back directions using COSMOS software. The materials used for the helmet is ABS and PVC.
