  This was a question unanswered for many days.... now have a look at it. This cannot be called as a simulation, but if you want to make an animation out of your modelled spring, this can help you out. I'll soon post the written tutorial.

  Tutorial: Simulation of a compression spring in Catia V5?

  1. Step 1

     Open a new file in DMU Kinematics-> insert->existing part (insert all the components made for the purpose)

     

  2. Step 2

     Insrt->new mechanism-> fix the bottom part

     

  3. Step 3

     Click on "prismatic joint"->in line 1:select the middle line about which the helix was created,in line2, select the bottom plate,in plane1 and 2 select the zx planes of both the components respectively as above.

     

  4. Step 4

     Check the result by simulating the components.

     

  5. Step 5

     Enter the part file which is fixed (here the bottom plate).Create the upper plane (as shown in figure) at the top end point of the helix parallel to the x axis.Exit the part. Again enter the part file which is movable (here the spring) and create a plane at the bottom point of the helix parallel to x axis.

     

  6. Step 6

     Remaining in spring part file , double click on "pitch". Now right click on the value.-> edit formula

     

  7. Step 7

     Now click on height and see that it is added to the place shown in the figure. Divide it by the no. of turns of the spring. I had 10 turns in my spring, so I divided it by 10.

     

  8. Step 8

     Now double click on height. Right click on the value-> measure between-> select the 2 planes created in the earlier stage-> ok

     

  9. Step 9

     Click on "update mechanism

     

  10. Step 10

      Now click on "simulation"-> activate sensors->set product/measure between/length to "yes" by clicking on it.

      

  11. Step 11

      Update the mechanism

      

  12. Step 12

      Now to make an animation click on "tools"->image->video

      

  13. Step 13

      Configure the video settings if required. Then click on record. See that nothing happens. Now click on the spring, still nothing happens. Now click outside the model area you'll see it recording the first frame.

      

  14. Step 14

      Now click on pause button. Simulate the model with only one step. Click on record again. Select the spring and click outside. See that it records a 2nd frame. Similarly proceed till you get the required frames to make an animation video. The last part of the video contains the animation which had 45 frames. Be sure to hide the sketches and planes for a better view.

     you can update measure between from:
     Tools > Options > Parameters and Measures > Measure Tools>automatic update in product

  I followed the procedures but does not work!

     does not create the phase of the update!

     see the video. i myself made it and no manipulation. ofcourse it worked for me and hence you see the animation at the end of tutorial. you might have gone wrong somewhere. please check the correct procedure again.
