Abstract
This work aims to apply the density-based topology optimization method to the design of pneumatic soft actuators. The approach employed involves the use of compliant mechanism formulations with pressure loading at input ports. The physical model used to represent the pressure loading is based on mixed finite elements. Besides our aim is to design pneumatic actuators, the same design was optimized for different fluids (air, water, and highly incompressible fluid) to evaluate the influence of the material properties in the optimization. We optimized a bending and a linear actuator considering solid isotropic linearly elastic material model and small displacement for the kinematic description. In both cases the convergence was easier for more incompressible fluids.
