Abstract

Aerodynamic drag contributes to resistance experienced by a cyclist when riding bicycle. The lower aerodynamic drag was required for helmet to obtained the high performance. The helmet surface was designed without air hole and fin shape which could not reduce attached airflow. Then, that helmet can‟t help to maintain airflow behaviour and improved performance. SolidWorks simulation was used to analyse the air flow behaviour via existing helmet by using method of Computational Fluid Dynamics, CFD. The best result of CFD was achieved and can reduce about 7.93% compare the drag force of existing design was 1.210 N. The result drag force of improved design bicycle helmet was 1.114 N. In conclusion, all analyse get the characteristic of aerodynamic and the effect of air hole and fin shape towards bicycle helmet are positive for airflow behaviour via bicycle helmet by addition of air holes and fin shape.
