The study of soft actuators has consistently presented a complex research challenge due to their inherently non-linear behaviour. These actuators, composed of pliable materials, exhibit distinct responses based on their geometric configuration when subjected to various modes of activation. Among these, soft pneumatic actuators (SPAs) stand out as a popular choice, thanks to their lightweight nature, impressive energy density, high power-to-weight ratio, straightforward design, and ease of operation. The current study aims to enhance the realism of simulations through a two-way Fluid-Structure Interaction (FSI) approach, linking Computational Fluid Dynamics (CFD) simulations with Finite Element Analysis (FEA) simulations via System Coupling. In this investigation, particular attention is given to the Soft Pneumatic Linear Actuator (SPLA), addressing a notable research gap in the existing literature. FSI of SPLA gives 79.61% increment in the axial deformation. The results obtained from this study offer valuable insights, enabling predictions about the deformation characteristics and guiding decisions regarding necessary geometric modifications for achieving desired behaviour. Importantly, this approach eliminates the need for costly and time-consuming physical manufacturing of SPAs, presenting a cost-effective and efficient solution for industries seeking to optimize their soft actuator designs.
