The work aims to investigate the collision and rebound behaviors of elastic thin-wall circular ring with low velocity impinging on ideal elastic column. In experimental tests, a high-speed digital microscope system was used to record the whole process of collision interaction of brass ring impinging on three kinds of elastic columns. In theoretical aspect, the modal superposition method and Lagrange equation method were applied to derive the governing equations of motion for the constrained motion stage and the free motion stage of the circular ring, respectively. The iterative relationship between the two sets of equations was then established, from which the whole process of collision interaction was described. The number of collisions increased and the non-dimensional rebounding time and coefficient of restitution decreased as the stiffness ratio increased. The critical stiffness ratio of multiple collisions increased with the increase of the thickness-radius ratio of the circular ring. The theoretical method successfully predicts the collision and rebound behaviors of elastic thin-wall circular ring with low velocity impinging on elastic column and can provide some theoretical guidance on the selection of geometric and material parameters in anti-collision structure and the selection of hammer head in experimental modal analysis.
