Two questions

system · October 21, 2008, 9:58am

Dear all,
I have two questions about humanbody in anybody model
system. I have known that some simple parameters could be revised in
anybody model system, such as the body mass, height etc.But now, I
want to build a specified person bodymodel in ANYBODY. Naturally, I
want to utilize the Humanbody in the repository.So the firstquestion
is that besides the preceding body parameters(body mass, height etc.)
I have mentioned, which bodyparameters also to be measured and
modified for my specified bodymodel ? As we all known, there must be
some differences for everyone and each muscle. So the second
question is about strength parameters. How to gain the exact value
of “StrengthParameters” for each muscle (or bone) and a spcecial
body? Maybe by some experiments or some formular calculation?
In brief, for example in the following script, why the value
of “SpecificMuscleTensionSpine” is 90 N/cm^2 but not 80 N/cm^2?

 AnyFolder StrengthParameters={
   AnyVar SpecificMuscleTensionSpine= 90; //N/cm^2
   AnyVar StrengthIndexLeg= 1;
   AnyVar SpecificMuscleTensionShoulderArm= 90; //N/cm^2
 };

Thanks a lot in advanceÂ£Â¡

Hi Changwei Xu,

The easiest way to model a specific person is to scale the body. The scaling
facility in AnyBody allows you to define the mass of the body, individual
segment lengths and the strength of the muscles is also scaled. There is now
a scaling tutorial available in our web site which we invite you to look at
( http://www.anybodytech.com/861.0.html ).

The parameters in the folder StrengthParameters are usually not needed to be
modified as the scaling already takes care of the muscle strength. But you
can use it to scale the general strength of the body in cases such like
modelling an old person: for example an old person will be weaker than a
young one of the same size, and the age parameter is not taken in account by
the scaling function. Or in the same way it can represent the low strength
in the limbs during the rehabilitation period.

Best regards,

Sylvain, AnyBody Support
