Is there a way to compress the spring (created using helix curve) in MOTION SIMULATION. 1

[PraveenKK]

Hi Folks.

I was looking for the procedure to compress the spring ( which is created using helix curve) and make length and pitch as variables) in Motion Simulation of NX.

I know that there is way to compress a body in Assemblies using deformable objects/parts. but i was looking to do the same in Motion Simulation,

Any kind of answer related to that are really helpful.

What is it you are looking for ?
Is all that you want to see the spring working?

You can simulate springs in the motion simulation but you will not see the model deform.
There is a difference between simulation and animation. NX Motion can simulate mechanical processes but not animate all involved elements, such as deformations.

( It would be "dangerous" to implement an "eye candy" deformation since people then would expect the animation to be physically correct. A true deformation simulation would in many cases require a complex calculation, which is what a FEM simulation can do. And yes, you can combine a Motion Simulation with a FEM simulation to see the combined result.)

I did many years ago use NX motion simulation to create a video which shows how a complex mechanism works.
In this i needed objects which looked like working springs. I cut the spring into 180 degree half's. ( i split the spring using a plane along the rotation axis) Then connected each half with a rotation joint. it looked ok but was quite some work.
That job was for animation purposes, not Simulation.
