1 Introduction

Three tanks are connected with two pipes. Each tank is initially filled to a different level. A valve in each pipe opens, and the liquid levels gradually reach equilibrium. Here, we model the system in MapleSim (including the influence of flow inertia), and also derive and solve the analytical equations in Maple.

Hi,

I have an inverse kinematics model for a double inverted pendulum. There are multiple solutions for each joint angles due to symmetry and I have to choose the appropriate ones. I thought I can use the previous choices and compare them with the current multiple solutions, so I could choose the ones which are closer to the previous ones. However, since the double inverted pendulum moves in in both region at the equilibrium, this aproach does not work. Could you advise...

I have just started using MapleSim 5 and running the examples I got the following notification and don't know how to resolve it (to what options are being referred to and what is infolevel?):

Compiling...

(in dsolve/numeric/RunSimulation) unable to compile, please check your options by running with infolevel[ToExternal]:=1;

Simulation failed.

Not sure what (in DNS/RunSimulation) means but it preceeds my "simulation failed, an error occurred" note.

I made a model with mapleSim, run simulation and the following figure was got

Here I have a question. I want to know the max value of this curve that will be used in other component as input in mapleSim. Is here a component in mapleSim or other mothed such as maple?

please help me. think you

On Monday, August 6 at 1:31 a.m. EDT, NASA will attempt the landing of a new planetary rover, named Curiosity, on the surface of Mars.  The Mars Science Laboratory project is managed by the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California, a world-renowned center for robotic space exploration and advanced science and engineering.  JPL recently began a widespread adoption of Maplesoft technology, and Maplesoft’s products are expected to help JPL save...

Hi,

The model that i uploaded (EqQui.msim) has a component with severall output and 4 inputs, but 2 of the inputs (LgKph2o and Lgkpco2) depends on one of the outputs. The 2 interpolation tables transfor the output variable (temperature) in this two inputs. All components works fine independtly (first "model", the one on the top), but if i link the exit of both interpolation tables mapleSim say it cant solve a lot of variables.

I am currently working on a MapleSim model that is similar to the Stewart Platform, yet less complex. I have built a tripod that is fixed to the ground with three legs connecting to a platform. Connecting the leg to the ground is a revolute joint and connecting the leg to the platform is a spherical joint. When I change the initial conditions of the spherical joint from 'Treat as Guess' to 'Ignore' 2 of the 3 legs will change orientiation. I'm not sure why this occurs to only 2 legs, can someone help me?

I have created a wheeled robot in MapleSIM for my bachelor thesis and for various calculations I need the location of the center of mass.  I am unsure of how to find this.  Could you please help me and explain how to find this?  Thank you for your help.

I have got the following instructions of computing the required trajectories (orbits). They have been done with Maple V3. I cannot get them going with Maple 16. I have just started with Maple and cannot see the mistake in the instruction. Can anybody help me? Thanks!

hi,

I am trying to make a simple model of a combustion. To start i am just calculating the composition of the products for a complete combustion and flame´s adiabatic temperature. The equations used to solve the model are:

equations:

nch4 = nco2;
2 * nar = 2 * nco2 + nh2o + 2 * no2;
7.52 * nar = 2 * nn2;
4 * nch4 = 2 * nh2o;
nch4 * hfch4 + nar(hfo2 + 3.76 * hfn2) = nco2(hfco2 + cpco2(Tad - 25)...

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...

Hi,

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?

Thanks for your help....
