Abstract

The purpose of this work was to develop a new 2D gymnast-high bar model with horizontal bar endpoint dynamics included. To this end, a three-spring high bar model was extended with a five segment gymnast model followed by evaluation and sensitivity analysis. Evaluation over more than a complete giant swing (420°) was favourable (bar position rms errors <0.017 m, center of mass angular position rms error <11°). Single parameter perturbations (10%) caused little deterioration in model performance (lower 180°of the giant swing-bar position rms errors <0.006 m, arms’ angle rms error <0.9°). Combinations of parameter perturbations gave bar position rms errors <0.008 m and arms’ angle rms error <1.8°. Model performance was most sensitive to errors in high bar stiffness values.
