If I have a MapleSim file that successfully runs and I want to manipulate the data and equations in Maple, how would I do that? I know how to link a MapleSim file to a Maple document, and how to pull out the system of reduced DAE's, ODE's, parameters, etc. My question is whether or not there's a simple way to have Maple solve those equations and be able to display the same type of data (graphs, export the numerical solution to the system to an Excel file, etc.) that...

Hi,

I need to get inverse kinematics model of a double inverted pendulum. I got a model but it gives error when I run. It seems to me that the inverse kinematics model is not quite right. If you are able to help me, I will be very pleased.DoublePendulumI.msim

Thanks for your help....

Hello,

I have to design a wheeled mobile robot for my bachelor-thesis. the robot should be controlled in Simulink. Therefore, I have to use the Simulink Component Block Generator. Outputs are: yaw angle/rate, absolute position in x/z and its derivatives, wheel angle and its derivative,steering angle. Inputs are one torque for steering and one torque for actuatuating for each wheel. -->6 torques (3 wheels). When I click on the "Generate and Compile...

How can we re-initialize a multi-body system, for example a three link pendulum, based on measurements obtained from various sensors? Can we generate a modelica custom component which has inputs from various sensors and the output is the re-initialized states for the multi-body system?

I have a system consisting of a multi-body system and various modelica/maple custom components. The problem is whenever I re-run the simulation even though all the simulation settings are same, the simulation results are inconsistent. There should be no difference between each simulation as all the parameters/settings are same. I am attaching two pictures which are both obtained from two successive simulations

Hallo Everybody!

I have a question concerning MapleSim5 and the "change of parameters during the simulation".

I am trying to build a kind of gantry crane, consisting of a vehicle with a pendulum. The mass on the pendulum can be pulled up and pulled down (the pendulum length can be varied). The inertia of the pendulum changes with this length of the pendulum. The pendulum is represented by a "Rigid Body". In this block it is possible to enter the matrix of inertia.

please in nead help in this aaplication (HydraulicsStewartPl) :

1-How do i change the position of platform in playback mode ?

2-How do i connect this model to the out side world

Hi everyone,

I've been able to generate equations of motion for my system. I want to linearize the obtained equations. How to do it? I've been trying to find some example on it, however, haven't been lucky as yet. Can anyone please help me with this? Anticipating a quick reply!

Regards,

I am trying to get the linearized model of a multibody system which has multiple inputs and multiple outputs. I initially used the "linearization template" of the MapleSim for an inverted pendulum, it worked fine. However, when I tried to get the linearized model for the double inverted pendulum, it gave this error message "problem at initial time: system is underdetermined; cannot solve for the following variables: 'Main.DFPSubsys1inst.eM_MyPendulum1_R1(t)'".

I am trying to extract the underlying equation for a simple operational amplifier circuit in MapleSim 5. The same process that I had used earlier for a simple resistor circuit (without opamp) worked fine and yielded equations. However, when I try to do the same thing with an opamp (configured to do a simple amplification of an input voltage) I get a blank "View Core Equations" box in the Equation Extraction attachment.

Thanks!

The input signal is given above. I don't kown how to get ti in MapleSim whether use custom component or not. Is there anybody can do me a favor. Thank you very much.

Does anyone know how to switch a joint between having a prescribed motion driver and acting as a passive joint? More specifically, I am building a bed of spring to serve as a model for haptic feedback on a Phantom Omni device. Therefore, I need to read the position of the device (which is not a problem) and then based on the position of the device calculate a force to feed back to the device.

Consider the simplified example below. In one situation I may need to give...

I have tf=0.04s but the probe plot only 0.02s at one simulation, 0.03s for another simulation ! How to oblige the probe to plot from 0s to 0.04s ?

Thanks

How would one set up a multispring model in maplesim?

Actually I don't know the exact model I want to try to explore yet, but I was wondering if someone could show an example of, let's say a beam with 4 springs attached offset to one end. On one end of the beam we inject vibrational frequencies and graph the output on the other end - doesn't matter which end - I imagine we could explore both from both ends. How could we set that up?

Here is my example picture.

Well, I'm trying to connect a translational spring to a revolute joint. But, I'm unable to do so. I'm new to MapleSim and I ain't a mechanical engineer either. I need you to help me a little. Anticipating a quick response!
