DO I NEED DMU KINEMATICS TO VIEW A SIMULATION? 2

[toyayo]

Hello everyone,

I am trying to find out whether I need to have the DMU Kinematics moudule/license? to view a simulation. I have the basic DMU package (cut 3D sections). Thanks

What type of simulation?

Sorry about that. It's just a stering column and I need to see the telescopic movement so that I can design the shroud around it.

Toyayo,

It sounds like you don't have the DMU Kinematics workbench, and you don't have a simulation already defined.
Without Kinematics, you still have several options to simulate the telescoping column:

1. You can use the compass to move the parts within the column. Double-click the red dot of the compass to move the parts along the column axis and a specific distance

2. You could add a offset constraint between the parts in the column, and vary the offset distance to extend/contract the column

(If you do have DMU Kinematics and a simulation has been created, you could save the simulation as an .avi file, and play it back without DMU Kinematics)

I'd use method 2 as described by jackk (not got a DMU licence). In assembly design, fix the column and then apply a concentricity constraint between the column and the shroud. Then if you use the Manipulation icon - select the Drag around any axis button (bottom right) and check the 'with respect to constraints box'

You then need to select an element on the shroud that's parallel to the axis of movement, which will indicate an axis line. Finally, just grab and drag any part of the shroud and it should hopefully move the shround up and down the column. The cancel button will return the shroud to it's original position. I used this method to similate a bonnet opening and the operation of the bonnet safety catch and it worked well. There's also a 'Stop manipulation on clash' button which you can select which basically does what is says.

Thank you for all the help. Managed to apply the constrains and was able to setup what I needed to see.
I also liked the "stop manipulation on clash".
Jackk, I could not see a "simulation" file in the data I got, how do I know if I have one? The .avi would be interesting to see.

I don't have one to check, but I believe the simulation would be listed at the bottom of the spec tree of the CATProduct. They are created with DMU Kinematics, Fitting Simulation, etc, and can be converted into a video format, such as .avi

Thanks for the feedback! Glad to hear you were able to get what you needed.
