An Experimental and Numerical Study of Deformable Bodies Contact

This study deals with the impact of a rotating disc elastically striking a strip. We establish an experimental setup including a disc with a throwing machine controlled by a dSPACE-Autobox to generate the translational and rotational motions of the disc, a properly fixed strip and a high-speed digital camera system with an image processing package to capture kinematical data of the disc. The effects of strip flexibility and disc initial normal velocity before impact are investigated in detail. For interpreting the experimental results a hybrid impact model is developed which can provide not only generally good predictions compared with measurements but also some insight into the influences of strip flexibility and disc initial motions.
