MapleSim Questions and Posts

I have created a model for a robot in Solidworks and have imported it into Maplesim using the CAD toolbox. The problem I have is that the robot has 3 arms that are supposed to come together on a central piece pictured below in figure 1, but attempting to simulate the model with all arms connected with a revolute joint as in figure 2 yields an error that says "The system is underdetermined" the location of the error is main.

For the purposes of the image below I only connected one of the arms, this allows Maplesim to run the file successfully.

figure 1 showing the central piece that the 3 arms are supposed to connect to.

 

Figure 2 showing the problem revolute joints circled in black, the error at the bottom and the setting of the revolute joint on the right.

 

Essentially my question is how do I get the model to work? I apologise if this problem is not terribly well demonstrated, this is my first post onto this forum so I am not sure of all the standards.

Dear MapleSoft,

 

Would it be possible you once design a MapleSim webinar for users with more emphasis on Modelica (language, examples, etc.), on how to build more complex custom components, not just a simple DC motor? I think this would be very useful and could extend / enhance the use of MapleSime even more.

 

Tx in advance,

best regards

How I can simulate control speed of car with sensor of speed, noise, feedback on maplesim?thanks

Does any one know if you can extract the linear graph from a Maple Sim model?  And by linear graph I mean the alternative to a a bond graph, not a type of plot.

I want to build a custom component by the material’s stress-strain curve ,for the component signal input is the x(t)(displacement-time curve), then I can simulate the material’s acceleration-time curve,the stress-strain equation , parameter and the custom component I built has been given in the picture,but the x(t) is same as the s[rel](t),so how to solve this problem? Thanks first.

 

 

 

 

 

Hello,

I have many tests to conduct on a MapleSim model. At each test simulations, I would like to change slightly some parameters.

As I have many tests to do (with different parameters), I would like to use a script so as to do like this :

Parameters test1
Launch MapleSim simulation
Store results of test 1

And so on ...

How can I do this kind of script ?

Is it possible to store the 3D animation results ?

Thank you for your help.

 

I'm trying to run c code generated from a simple MapleSim example (Spin Up Beam). To makes things even simpler, I set the input real expression to just time, and changed the input function in my c code to:

static void inpfn(double T, double *U)
{
U[0] = T;
}

I set all the state variables to 0 for the initial conditions. I ran the code and my output doesn't resemble the MapleSim output at all, and I'm getting errors. So my question is about the state variables, which I initially set to 0:

* State variable(s):
* x[ 0] = `Main.SpinUpBeam.FB3.uf1`(t)
* x[ 1] = diff(`Main.SpinUpBeam.FB3.uf1`(t),t)
* x[ 2] = `Main.SpinUpBeam.FB3.uf2`(t)
* x[ 3] = diff(`Main.SpinUpBeam.FB3.uf2`(t),t)
* x[ 4] = `Main.SpinUpBeam.FB3.vf1`(t)
* x[ 5] = diff(`Main.SpinUpBeam.FB3.vf1`(t),t)
* x[ 6] = `Main.SpinUpBeam.FB3.vf2`(t)
* x[ 7] = diff(`Main.SpinUpBeam.FB3.vf2`(t),t)

What do these represent for this flexible beam (FB3)? I.e. what is uf1, uf2, vf1, vf2? Should they be set to 0, or no?

Thanks.

Hello,

Thanks to the function Exports, it is possible to see the differents functions and modules which are in a module.

For example, I find in the module GetMultibody a module called GetLGM which permits to conduct some linear graph analysis. I'm interested by this module.

However, to my knowledge, I didn't see any help on this module.

How can I do so as to understand the inputs to give to the functions of this module in order to use the functions of this module ? In other words, how it is possible to use functions from a module when you don't have any help at your disposal ? 

Thanks a lot for your help.

Hello,

I use for the 3D visualization the component CAD geometry with STL files.
My STL files are created from CATIA with parts mesured in mm.
In MapleSim, in order to keep mm, I have, of course, to set "mm" in the inspector tab of the components "CAD geometry".
But, I have also to put the scale factor to 0.001.
I don't understand why I should to set it to 0.001 because :
- the CADs from CATIA are in mm.
- and the option in the inspector tab of the components "CAD geometry" is also in mm.
Would you have some precisions about the scale factor for the "CAD geometry" element ?

Thank you for your help.

When I run a simulation (i.e. Double Pendulum Example) MapleSim crashes with no errors or dialogues - completely shuts down. The simulation seems to compile ok, then as the plots are opening it crashes. My video card driver is up to date. Anyone know how to fix this?

Thanks.

in maplesim 7

when run example below

http://www.maplesoft.com/products/maplesim/modelgallery/detail.aspx?id=120

got error in linear_string and linear_string2

prototype must be a structured record type or a record, but received squeezed

There is a problem with the modelica code for custom component named CorneringForce
Regenerate or delete this component to correct this porblem....

........Matrix2Euler

i click the web said USD99

but after click into it, academic version is USD1,555

there are commercial version, academic version , what are difference?

i see that there are self balance robot and humanoid walk robot

what are the specification of size, length of components are they?

if simulate robot hand which has a string make a tension to grip object

what kind of string is it? where can buy robots components which fit the simulations it do?

will maplesoft cooperate with 3D printer to fit the reality of robots?
