There is a example "3D rigid slider crank" in the MapleSim examples. Replace the "crank" and the "rod" with flexible beam, turn it into a flexible system, how to do that?

Thank you very much!

Thank you very much.
As you say, the rigid body frame components, can define the end points of the link. But what about "the flexible beam", how to define its endpoint? The "maplesim help"  say "the beam is straight and its neutral axis is aligned with the x axis of the primary frame", then its deformation is measured.  I think in a system, the flexible beam is used together with the rigid body frames, but it always point to the direction of the x axis,...

For example, the simple pendulum length changes by the law

l = l_0+a*t

where a - constant, t - time, l_0 - link length at t=0.

How it is possible to model such system? Is it possibly to change r_XYZ in Rigid Body Frame under this law or it is necessary to go by another way?


I have got few quick questions once i have gone through the features of MapleSim connector and here are they.

  • Can we use the S-function created by MapleSim with Targetlink
  • If I am doing the HIL simulations, how does MapleSim take care of solvers. Do we need to write the device drivers and tlc files or the tool takes care of it.
  • How do I go about doing HIL simulations if my model is discrete.

Would appreciate if...

How can I save the simulation data from a MapleSim model into a file?
How can I record the 3D visualization that MapleSim produces? (into an .avi file, for example)

I am building a robot arm,now I want to replace the rigid arm with the flexible arm. How can I control the arm's form?

Thank you for your post! But I`m newbee in MapleSim and have one stupid question. Can you explaine how to compute the g-force magnitude and feeding it into the TSDA? May be, you post msim-file or screenshot?

I need to use the flexible beam in my model. I want to know if the component's correctness can be guaranteed, but I can't find any correlative documents or thesis, only find an article titled "Dymola – Flexible Bodies library". Is the flexible beam in maplesim similar to this? based on the modelica library? applied the finite element method? Some detailed information is very helpful.

Is there a possiblity to create custom multibody components with the custom component template? Is there another template available for this purpose, or do you propose another solution?

Thanks a lot,


I would like to translate Maple's products into Russian and to help russian users in Maple's education.

Whenever I have 2 instances of the rotational move block in a model, mserver.exe crashes when I try to run the simulation. Why is this?

I want to define the inertia matrix of a body within a subsystem as a subsystem parameter. I can define constants (like mass), but I cant define the 3x3 inertia matrix. It looks like MapleSim returns a dimensional error when I try to simulate the model. How can I assign the inertia of the rigid body to a parameter?

I am trying to create a Simulink component block from a MapleSim subsystem. I have one input to the subsystem, and the Specified Inputs and Outputs section of the MapleSim Connector worksheet also shows that the subsystem has one input. However, When I export the model to Simulink, there is no input port, just one output. How can I fix this?

Current I need model a mechanical system with kinematic loop. In Maplesim4 the calculation speed is too slow. I need to use this model in HILS. How to solve this problem? I check the 'four bar' example, It's too slow(simulation 1 second, 40second is needed, Intel xeon 3GHz,2cpu) Anyone who can help me? Thanks! Wander
