Abstract:
Motorcyclists are particularly vulnerable to injuries in the event of a crash due to the lack of
physical protection compared to other vehicle occupants. Impact protectors are designed to
mitigate the risk of injuries by absorbing and dissipating the impact energy. The selection of
appropriate materials for impact protectors is crucial to ensure their effectiveness. This study aims
to develop a predictive model using the XGBoost algorithm to assist in selecting the most suitable
materials for motorcyclists' impact protector design.
The model incorporates material properties and impact testing data to predict the performance of
various materials under different impact scenarios. A comprehensive dataset was compiled,
including material characteristics such as density, hardness, and tensile strength, as well as impact
test results measuring parameters like peak force, energy absorption, and deformation.
The XGBoost model was trained and validated using the collected data. The results demonstrate
the model's ability to accurately predict the performance of materials in impact protectors, with a
high degree of accuracy and reliability. Feature importance analysis was conducted to identify
the most influential material properties in determining impact performance.
The developed predictive model offers several advantages for the design and development of
motorcyclists' impact protectors. It provides a data-driven approach to material selection,
reducing the time and cost associated with traditional testing methods while ensuring the safety
and effectiveness of the impact protectors. The model can be further refined and updated as new
data becomes available, continuously improving its accuracy and reliability.
This study highlights the potential of machine learning-based predictive modeling in optimizing
material selection for impact protector design. The results emphasize the importance of
integrating material properties and impact testing data to develop a comprehensive understanding
of material performance under different impact scenarios. The predictive model presented in this
study serves as a valuable tool for designers and engineers seeking to develop effective and safe
impact protectors for motorcyclists and other applications.
