Force generation capacity of the cervical spine model

Main Forum
1

Hello,AnyBody,
I am new to AnyBody. I am working with AnyBody to simulate the cervical spine movement.

Recently, I read the website “A detailed rigid-body cervical spine model based on inverse dynamics” from Mark de Zee. In the website, Mark calculated the maximal force generation capacity of the cervical spine model in all directions to validate the neck model. But when I load the example MaxForceNeckModel, I can’t get the correct values of maximal force generation capacity of the cervical spine model.

My question is that: how can I get the correct values of force generation capacity in all directions to plot the figure in the website?

Many thanks for your help and your time in advance!

Dear Qing Feng,

I think that the model in the repository uses a different muscle recruitment algorithm than the one used in the abstract.

Try to switch to the min/max criterion.

Greetings,
Mark
