Testing and Analysis of Spherical and Aerodynamic Helmet in open Circuit Low Speed Wind Tunnel

Abstract

The main aim of the helmet is to provide the safety and protection for riders from head injury. The shape, size and design play important role in aerodynamic drag. The drag force resistance the helmet against the neck portion and create unstable effect which cause neck pain. This paper discusses a testing and analysis of model of motorcycle helmets. Two types of helmets spherical and aerodynamic shape are used for analysis. These models of helmet were tested in a wind tunnel. The open circuit low speed wind tunnel was used to measure pressure at a range of wind speeds (5m/s, 7.5m/s and 10m/s) and different pitch angle (0°, 15° and 30°). The pressure was calculated. I am tried to adding some modification for batter performance of helmet. After the complete the experiment model works properly and I found all solution. The experiment is very helpful to improvement of helmet and aerodynamic work. It is definitely very useful for primary research.
