Hi everyone,

I need to assign the output of the timer block to a variable which is then will be used in a trapeziod signal to add a time offset. Please see the visual below.

Thanks for your time,

Hello guys..

I am a master student and I am interested in modelling of six dof industrial robots. in this study, ı firtsly import autocad model into Maplesim and add revolute jont between each  two link. I want to coriolisis matrix from the model with inertia matriix . I wait your helping and thanks for your interest   

What shall I do to install Maple 15 and MapleSym 5 in a Windos 10 environment.

I find the procedure in Maplesoft site up to Windows 8.

May I follow it for Windows 10.

Thank you for any help. Kind regards

Hi,

I get an error when I try to create a modelica block including a piecewise function with one of its expressions including csgn function.

similarly when I use the piecewise And for its conditions.

are these not supported in Modelica?

I  encountered a non-integrable integral in the process of solving the following process, . How to achieve its numerical solution? Such as in a looping   code：

#######
pa[i] := pa[i-1]-(Int(subs(t = tau, Lpa[i-1]+Na1[i-1]-Na2[i-1]), tau = 0 .. t)); 

pw[i] := pw[i-1]-(Int(subs(t = tau, Lpw[i-1]+Nw1[i-1]-Nw2[i-1]), tau = 0 .. t)); u[i] := u[i-1]-(Int(subs(t = tau, Lu[i-1]+Nu1[i-1]+Nu2[i-1]), tau = 0 .. t))；

######
Detailed code see annexBC2.mw

Hello every one,

I'm using Maple to create a compiled program of my model Maplesim. I had a error with "getcompiledProc" command, which is :

Error, (in GetCompiledProc) non-numeric initial condition for `Main.RAB.value`(t): Float(undefined)

the "Main.RAB.value(t)" represent a probe used to visualize an output of my system.

Does anybody had a such error ?
Thank you for your responses.

Hi,

I am trying to download some MapleSim Robotic models from the Maplesoft website but I have 'Invalid File Format' error. Could you help please?

Dear forum users/ admins, I have some questions regarding the wind turbine vibrations model based on the MapleSim gallery. I am a new user, went through some tutorials and am currently trying to understand how the system works.

I will try to deliver my questions based on the pictures shown below:

 1. After running the model, 2 results were shown. One is "Latest Results" and the other is "zeta=0.01". Based on the images above, there is a comment that the result was dated Feb 14 2013. Is this the result on which the day the model was created? If it is, is it programmed to be in the result file everytime the simulation runs?

2. If I untick "zeta=0.01", a red graph appears, which says Latest Result. But the graphs are not labelled. How can I label this graph in MapleSim? 

3. I would also like to ask, what type of vibrations are occuring in the model, and what does the Deflection-Time graph means. Why does the deflection occur highest at 120s and then drops? Is it because the tower becomes stabilized after a while?

4. I understand that the model is run by a signal and fed into a speed component. May I know what is the f(critical) is, and how it affects the system?

5. From the Ramp signal, there is a "height" value. The pre-set value is 10. After changing this value, to lets say 50, the maximum deflections occur at a an earlier time as shown in the figure below:

6. I would like to understand how does the ramp affect the maximum deflection time that occurs.

Thank you very much!

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

you write:

where i can found oscilloscope icon for cisuit simulation?thanks

why the current luca_amplificatore_retroazione.msimand voltage is egual to zero?

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.
