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

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.
