Activation data for Hill Activated muscles!
Submitted by bechuv on Tue, 05/19/2009 - 16:50
Dear All,
I want to build my own model in LifeMOD and run forward-dynamics simulation directly, not through the inverse-dynamics step. But I get problem when building the full body Hill-based muscles. I need to have activation curve to fill in "GLOBAL MUSCLE ACTIVATION DATA" box. Unfortunately, this file is not available in LifeMOD. If someone has this file, please send it to me. If not, please instruct me how to create activation curve (spline).
Thanks in advance.
Best regards,
KimTho

Hi Kim,Check out the "Antago...
Check out the "Antagonistic Muscle Effects" demo - it's a good demonstration of how to set one up. The demo uses a fairly simple activation curve, but you could also import a more complex data set (such as recorded EMG signals) and use the imported spline to do the same thing.
Do be aware that the results may not be what you expect; getting EMG or artificially created splines to work as an input into a model is no trivial task in any modeling scenario.
Have a good one,
