Summary: Planar spiral springs are crucial for miniaturizing motor-based elastic actuators. However, the stiffness calculation of the spring arms using beam bending theory leads to significant errors compared to finite-element analysis (FEA) results. This study trains two Gaussian process regression models to correct this error term in the stiffness calculation of spring arms and complete springs. The models are validated through simulations and the design and manufacture of a planar spiral spring for a powered ankle-foot prosthesis.

Summary: In this study, a musculoskeletal finite element model of a rat knee joint was used to evaluate cartilage biomechanical responses during a gait cycle. The results showed that simulating anatomical and locomotion characteristics accurately estimated tissue responses such as contact pressures, stresses, strains, and fluid pressures. This approach is important for investigating the effects of gait abnormalities on the adaptation and degeneration of rat knee joint tissues and could contribute to understanding the biomechanically-driven mechanisms of osteoarthritis progression as a consequence of joint injury or obesity.

Summary: 3D printing is the optimal method for producing frame parts of powered ankle-foot prostheses, but the compressive strength of the 3D-printed parts must be ensured. This study investigates the impact of infill pattern and density on compressive strength, using a carbon fiber-reinforced nylon material and following ASTM D695 compression test standard. Results show that specimens with higher mass exhibit greater compressive strength, and triangular fill patterns offer higher compressive strength than rectangular and gyroid fills at the same mass. Compared to solid fill specimens, triangular fill specimens provide more compressive strength per unit mass. Based on the findings, a 41% triangular fill is chosen for manufacturing the supporting part of the powered ankle-foot prosthesis, meeting the design requirements with a strain of 1.32 +/- 0.04% under a compressive load of 1225 N. This study provides evidence for the application of 3D printing in other contexts requiring compressive strength.
