Introduction

Bicycle helmets are essential protective gear for cyclists, designed to safeguard their heads from potential impacts. Unlike motorcycle helmets, bicycle helmets are designed to withstand lower-speed impacts, typically occurring on the sides and back. To comprehend the pressure and strain experienced by the helmet during a collision, a simulation and experimental test are necessary.

Background

Bicycle helmets are designed to provide optimal protection for cyclists. However, the materials used in their construction can significantly impact their performance. In recent years, researchers have been exploring the use of natural fibers, such as oil palm empty bunches, as a reinforcing material in composite materials. These fibers offer several advantages, including being environmentally friendly, lightweight, and strong.

Methodology

This study simulated the impact load on a bicycle helmet made of polymer foam composite material reinforced by oil palm empty bunches. The helmet model was created using SolidWorks 2013 and simulated using Ansys 14.0 workbench based on the element method (FEM). The simulation results were then compared with the experimental test results.

Simulation Results

The simulation results showed that the free impact test, where the helmet was dropped from a height of 1 meter with a speed of 4429 mm/s, resulted in a maximum pressure of 1,405 MPa on the side and 0.938 MPa on the back. The maximum strain on the simulation was 0.04 on the sides and 0.043 on the back.

Experimental Results

The experimental free impact tests showed a pressure of 1,029 MPa on the side and 0.683 MPa on the back. The difference between the simulation and experimental results was 0.091 MPa or 9.73% for the sides and 0.08 MPa or 13.26% for the back.

Discussion

The results of this study indicate that the use of oil palm empty fibers as a reinforcing material in a bicycle helmet has the potential to produce strong and durable products. The simulation and experimental tests showed that the helmet was able to withstand the impact load well, with the simulation results closely matching the experimental results.

Deeper Analysis

The difference between the simulation and experimental results can be influenced by factors such as the accuracy of the model, material, and manufacturing processes. However, the use of oil palm empty bunches offers several advantages, including:

Material Advantages

Environmentally Friendly: Natural ingredients that are easily obtained and renewable.
Lightweight: Offers comfort for the driver.
Strong and Durable: Providing optimal protection.

Conclusion

This study succeeded in showing the potential of oil palm empty bunch fibers as a bicycle helmet amplifier material. The simulation and impact test indicate that this material has the ability to withstand the impact load well. Further development and optimization of helmet design with this material can produce products that are safe, environmentally friendly, and affordable.
