NUMERICAL APPROACH FOR ANALYZING 3D-PRINTED FINRAY SOFT GRIPPERS WITH ARTICULATED CROSS BEAMS
Abstract
Soft robotic grippers inspired by the Fin Ray Effect have gained attention due to their ability to gently interact with objects. This study presents the design and 2D numerical analysis of a three-jaw 3D-printed soft gripper that includes articulated cross-beams. Opposed to existing simulation methodologies, the work focuses on computational efficiency and result accuracy by employing simplifying assumptions. The assembly was fabricated by using ABS via material extrusion. Validation against experimental data proved angular deformation deviations below 5%, confirming the accuracy of the simulation model. The gripper effectively adapts to the geometry of the objects while maintaining structural resilience. These findings highlight the efficiency and accuracy of the numerical approach, supporting rapid design iterations.
