Description
Summary:A finite element (FE) model of the THOR lower extremity (THOR-LX) was developed to enhance research using the THOR-LX. A three-dimensional representation of the physical THOR-LX was created with the same functionality: 3-axis ankle rotation, compliant tibia element, Achilles' cable, and deformable skin. The model outputs the same measurements as the THOR-LX hardware. The completed finite element model was correlated with the physical THOR-LX by simulating ten physical experiments and comparing the results. It was concluded that the FE model may be used to reasonably predict the results of physical tests performed with the THOR-LX.
