Investigate the biomechanical requirement of your target activity. Simulate your target users performing the activities. Compute individual muscle forces and metabolism along with joint contact-forces and moments. Compare the biomechanical requirement of your target task with a baseline (such as ergonomic standards). Identify criticalities that could be supported by a wearable assistive device, robot, or both passive- and active exoskeleton. Quantify the need of an assistive device and estimate the required assistance. See also AnyBody for Ergonomics
Examples of modeling and simulation of assistive devices
- Augment laboratory and field studies with biomechanical analyses.
- Use simulation studies as in-silico evidence of the efficacy and safety of your device.
- Supplement functional and safety portfolio of your device with simulations studies.
- Test your assistive device’s fit and support through population-based simulations.
- Investigate how different mechanical design parameters can affect the user.
- Evaluate changes in the internal body loads (e.g., muscle activities, joint reaction forces, compression forces etc.)
- Simulation-based design of exoskeletons using musculoskeletal analysis
- Modeling and simulation of a lower extremity exoskeleton
- Modeling and simulation of an upper extremity exoskeleton
