Data Analysis of Biomechanical Dynamic Modeling of a Prosthetic Running Blade

Abstract

This study presents a comprehensive data analysis of the biomechanical performance of prosthetic running blades, utilizing vast data obtained from finite element simulations to elucidate the dynamics of force and energy under operational conditions. The primary focus is on understanding the behavior of these prosthetics at a speed of ‘1 m/s’ and exploring the stability and fluctuations of various force and energy components. Key findings reveal that the kinetic energy of the blade and the total system energy exhibit minimal fluctuations, indicating a stable system behavior under the tested conditions. The normal contact force Fc shows a significant dynamic response, while the normal velocity Vy maintains a consistent downward trajectory, and the tangential force Fx remains essentially constant. Notably, a strong positive correlation between the force components Fc and Fx is observed, suggesting a synchronous relationship in their magnitudes. Additionally, a moderate negative correlation between the normal velocity Vy and the kinetic energies of the blade and system is identified, highlighting intricate interdependencies. This research contributes significantly to the understanding of prosthetic running blades, offering insights crucial for their design and optimization. The correlations and patterns identified underscore the need for further investigation into the causal relationships and practical implications of these dynamics in prosthetic technology.
