Vibratory finishing co-simulation based on ADAMS-EDEM with experimental validation

Vibratory finishing has been widely used for surface finishing, cleaning, deburring, deflashing, and stress relief in industry for the past 60 years. In vibratory finishing, the motion behaviors of granular media, determined by a vibratory excitation system, dictate the material removal from and surface quality of workpieces. In this study, a dynamic bowl-type vibratory finishing machine model was developed using ADAMS software. The behavior of the granular media in the vibrating flow field was simulated and analyzed using the EDEM software. The add-in EALink was used to transmit data between ADAMS and EDEM. For model verification, the vibration amplitudes of a container were experimentally measured using acceleration sensors. The contact force of the granular media acting on the workpieces and the velocities of the granular media and workpieces were obtained through co-simulation. Co-simulation can be used to estimate the uniformity of processed workpieces. Finishing experiments were conducted for comparison with co-simulation results using workpieces fixed to the inner wall of the container.
