Abstract

Motorcycle helmet is one of the important road equipment while riding, not only protect rider`s head from road accident impact, but it also be a major factor to cause the accident by determining the rider focus on the road, in term of inner space condition of the helmet. A good motorcycle helmet ventilation system helmet will always ensure the rider in an optimum riding condition. In this case study, an analytical study will be carried out in order to identify the heat released by rider head and the heat absorbed by the helmet outermost surface from surrounding. Computational Fluid Dynamics (CFD) method is chosen to solve this problem. This research conducted based on Physiological and Cognitive Effects of Wearing a Full-Face Motorcycle Helmet Journal by Cornelis Peter Bogerd .The process phases begin with pre-processing, followed by solution and ended by post-processing phase. A human head model, motorcycle helmet model and air box model constructed by using Computer Aided Design Software(CATIA), which are then exported into ANSYS-Fluent Software to solve and interpret the result data in form of graphs and contours. From the tabulated data, the maximum temperature and the minimum temperature will be determined. Due to the result obtained, several recommendations also proposed in order to ensure better ventilation system in future.
