Coupling Multibody and Granular Dynamics: Experimental Validation

Multibody systems can interact with other systems or with the environment via contacts.Such interactions can be solved by different techniques such as the co-simulation process, or a mono-lithic solver. In some fields of application specific treatments are needed for example when the contactsare stiff and numerous, and when vibrations dramatically impact the behavior of one system. For theseapplications, dedicated solving strategies have to be applied. To check the coherence of such strategywith the real process, we developed an experimental setup involving a multibody system blending agranular media. The proposed planar experiment consists of a modified four-bar linkage blending aset of disks contained in a vibrating box shaked at different frequencies. The experiment measures theinteractions between both systems at different frequencies via a telescopic bar included in the four-barlinkage.
