Hello My friends:
Now I say something about what I want to do. I want to know the transmissibility
in the human body in special conditions.
an example firstly,.
there two mass points which are point1 and point2. And it is connected by a
spring which elastic parameter K is 10N/m.
If a motion is input on point1, then output of point2 could be got. Based on
those, transimissibility could be found between point1 and point2.
In the following I introduce about what I want to get by using anybody system.
you know, in the system anyMuscleMode3E are included ,mentioned on Page 130
in The anyboyd modeling system turorials (V 3.0).
The class have some special parameters such as contractile element,
serial-elastic element and so on.
So I want to use this class to develop a standing model for studying the
transmissibility.
In my opinion, if a input on the foot of a standing model in anybody system
using the anyMuscleMode3E class, the output of other part of the model
could be got. when the input is a motion depending time, the output of a segmant
of a joint in the model could be a motion. And the out putmotion
should be different from the input. The difference between the output and the
input is what I want to know. also the muscle forces output could be learned.
best regards
yours yuening

Hi Yuening
This problem is not so well suited for the AnyBody modelling system, I
believe.
I am not entirely sure what you mean by transmissibility? , but if you define
the transmissibility as a function of input motion and output motion, then
it can not be done in AnyBody I guess. This is because that the input to the
model is the motion, so the motion will always stay as it has been defined
in the input. This will make the transmissibility impossible to calculate?.
Please if possible try to explain more about what you would like to
calculate? Frequency range etc.
Best regards

Hi Christian!
what I want to do is a standing model with vertical vibrating
conditions by anybody. According to it, I 'd like to get the
transmissibility of vibrations,transfor mation of some special muscles
and so on.
So far as I know, AnyBody modeling system has the
clacss “AnyMuscleModel3E” with some parameters. What I want to do is
by using this class to set up a model and learn about the vibrate
transimissibility. Could it be done?
Wish you a good weekend.
yuening, polyu
