Area of Science:

  • Physics
  • Biomechanics
  • Sports Engineering

Background:

  • Pekalski's (1990) mathematical model for arrow flight lacked completeness.
  • Existing models did not fully capture the complex dynamics of arrow launch.

Purpose of the Study:

  • To provide a complete description of Pekalski's mathematical model.
  • To introduce improvements for enhanced realism in arrow flight simulation.
  • To refine the understanding of the bow-arrow system for optimal performance.

Main Methods:

  • Developed an advanced mathematical model for bow dynamics to predict acceleration forces.
  • Modeled the contact between the arrow and the grip, including the pressure button as a unilateral elastic support.
  • Validated simulation results against experimental data.

Main Results:

  • The enhanced model demonstrates satisfactory conformity between simulation and experimental outcomes.
  • The model accurately predicts that the arrow detaches from the pressure button before leaving the string.
  • The improved model provides a more realistic simulation of arrow dynamics during launch.

Conclusions:

  • The enhanced mathematical model offers a more accurate representation of arrow flight dynamics.
  • This refined model can be utilized to optimize the adjustment of the bow-arrow system.
  • Further research can build upon this model for advancements in archery technology and performance analysis.
