In MapleSim, it is possible to constrain a rigid body in a multibody system to an arbitrary constraint? 

Similarly to how a mass at the end of a simple pendulum can only move along a circle defined by the length of the pendulum, I was hoping to constrain one to a shape like an ellipse or sine wave.  I could then give it initial velocities and see how it would move along the shape over time.

I'd like to be able to define this constraint with an equation. ...

im interested to know if there are developed MapleSim examples of water level control in a tank

MapleSim Tutorial Error!...

May 23 2013 bornag 5 MapleSim

Some errors in MapleSim Tutorials! While I was working with MapleSim tutorials, I have encountered some problems that the results did not match the answer. I have uploaded the files, that I have worked on, in a zip file to this address (http://www.mediafire.com/download/2pirvfbawyjfa18/MapleSim_Projects.zip). The problems are as follows:

1. Based on video tutorial on this page (

I have been trying to figure out how to use the flexible beam properly. I'm looking for a clear example on how to actually use this component. I have had no luck so far. I must be be missing something. 

 

The current example, http://www.mapleprimes.com/questions/94996-Flexible-Robot-Arm, does not really show much. 

 

Does someone have a simple example? Perhaps using the Flexible Beam as a cantilever, with one end fixed...

Hello,

I've been working on interacting with the MapleSim optimized C code (first post was here: http://www.mapleprimes.com/questions/145427-MapleSim-Connector-C-Code-Api?sq=145427) and two manuals were recommend to me to read, which were very useful. I ended up writing up an alternate implementation of the main method described in the one manual (http://www.mapleprimes...

Hi,

I've been trying to manipulate the equations of a mechanism that I've exported from MapleSIM.  The system equations contain 4 differential ordinary equations, and 6 algebraic equations.  In MapleSIM it simulates fine, but I'm having problems simulating it in maple alone (without multibody exports).

I've tried solving the initial value problem by replacing all the time dependant variables with constants, (and as this is a dynamics problem) I supplied...

Hello, 

 

I'm importing some other modelica models from other softwares (like open-modelica and dymola) inside maplesim. I can work in a full compatible code, except for the lookup table. Some of the models I'm importing as a library uses the standard lookup tables (not the ones given by maplesim) - I tried to run those standard lookup tables (from the modelica library) in maplesim, but it does not work.

 

Is there a way to solve...

Hello!!

 

I have modeled a 3DOF manipulator with crank-arm type actuators in maplesim!!!

It simulates the model... but when I "Create Attachement>Equations" and when I click on "load selected subsystem"... it starts evaluating but never gives me equation... I have waited for almost 2 hours but no luck!!!!

Any idea what should I do to get equations for this model??? 

 

P.s. I have attached the moel!!!

I have a PWM signal in MapleSim and want to have a spectrum analysis of it. The time domain signal should be transfomed into a frequency domain signal, to get the harmonics of this signal.

My first intention was to bring the MapleSim signal to Maple (Attachment->Worksheet->LinkModel->Simulate). Then I had a 2x1000 Matrix which i want to transform with a FFT. My problem is that it doesn´t work. How can I get a spectrum plot of this Matrix or function?

MapleSim 6.1 is here...

MapleSim 6.1 is now available.  MapleSim 6.1 provides improved performance, more tools for programmatic analysis and custom components, connectivity enhancements, and more.  Here’s a sampling:

  • For all models, the model pre-processing phase is more efficient, so your simulation results appear sooner.
  • New API commands make it easier to analyze the parameters in your model programmatically. These commands can take advantage of the full...

Hello,

I have a model in MapleSim for which I've generated the optimized C code using the connector toolbox, and I'd like to work with it directly. I was wondering if there is any documentation or examples of how to do this? I haven't been able to find any online.

Thanks! 

Hi,

A right click on the visualization CAD geometry icon, attaching an STL file, activates a pop up list of options. One of the options is "make rigidbody". The units are for the MKS system. I must be doing...

Hi

Can I have an example of inverse dynamics?

 

Thank you,

matlab to maple...

hello;

i want to rewrite the following matlab code to maple13

L=10*ones(2,m),L(1:2,1)=[90;90];

v(1:2,1:m)=[sum(L(:,1:m)),sum(L(:,1:m))];vv(1,1:m)=v(1;1:m);

this is a piece of program

Bonjour,


Qui peut m'éxpliquer l'algorithme de division d'un polynôme P(X,Y) sur un polynôme Q(x,y) ?


Avec mes plus vifs remmerciements,
Raymond Gérard.
