Explore your assistive device design ideas during the conceptual state of your design phase by modeling different assistance concepts before beginning virtual prototyping. Investigate if your device concepts reliably meet their biomechanical expectations. Compute internal joint loads, stress redistribution, and compensatory mechanisms inside the human musculoskeletal system, and digitally test and optimize your exoskeleton concepts with AnyBody Modeling System. Compare with and without exoskeleton assistance concept and define assistive torque requirement and related key exoskeleton specifications.
Examples in modeling assistive device design ideas
- Compute ideal assistive force or torque requirement.
- Apply idealized assistance directly to joints.
- Model and test different assistance concepts.
- Evaluate changes in the internal body loads (e.g., muscle activities, joint reaction forces, compression forces etc.)
- Analyze internal body load redistribution due to different assistance concepts.
- Investigate how different mechanical design parameters can affect the user.
- Simulation-based design of exoskeletons using musculoskeletal analysis.
- Modeling and simulation of a lower extremity exoskeleton.
- Modeling and simulation of an upper extremity exoskeleton.
- Simulation-based design of exoskeletons using musculoskeletal analysis.
“The AnyBody Modeling System can simulate trunk muscles that cannot otherwise be measured by normal myoelectricity. In addition, it can calculate joint forces that cannot be captured easily, which makes the software essential for correct estimation of the effect of our exoskeleton. The results and visualizations are additionally used in our promotional videos and has received great feedback from our customers.”
