Abstract
An experimental modal analysis was performed on an existing basketball goal, with the modes, natural frequencies and damping ratios identified. On this basis, a numerical model was created, employing the finite-element method. Due to the correlation between the experimental and the numerical results, the model was accepted as valid. Subsequently, this model was used to analyse the transient response that occurs when a fully loaded goal suddenly becomes unloaded. The resulting oscillation was compared to the valid standard for this type of sports equipment.
