Abstract

A safety bicycle helmet is one of the safety gears for cyclist to protect from head injury causes of impact in crash events. Impact is the collision between two bodies and is characterized by the generation relatively large contact forces that act over a very short interval of time. This project is applied for bicycle helmet design simulation to analyze the effect of impact from various angles and to test the energy absorption between existing and new natural composite using finite element analysis in Solidwork. Currently, there is no research to compare the mechanical properties in between synthetic bicycle helmet and non-synthetic bicycle helmet. Besides that, Solidwork 2016 software was used in this project as a medium for oblique impact simulation. The velocity of impact used was 19.9 meter per second used from our own national track cyclist with the recorded time of 10.073 seconds over the 200m. Bicycle helmet with hole design has an achieve target to get more maximum Von Mises stress value at 1.84E+08 Pa than the bicycle helmet with fin design at 1.79E+08 Pa. Based on the discussion, bicycle helmet with hole design for natural composite provide better energy absorb compared to helmet with fin for existing material. A track cyclist can save from head injuries as the effect of energy absorbed from the impact simulation is nearly same with the existing material.
