Hello,
I have a problem that has been bothering me for a long time, and I hope someone can help me out.
Suppose I have three objects A, B, and C. A and C are connected by one cable, which is easy to achieve by using belt-cable end. However, now there is a hole in the center of B, and this cable needs to pass through this hole. How can this function be achieved or what constraints are used?
Thanks in advance!!!

To constrain a cable to pass through a hole in an object in Simscape, you can use a combination of Contact Force and a Constraint block.
  1. Create a Simscape model with three Solid blocks for objects A, B, and C. Use a Belt-Cable block to connect A and C with a cable. Create a hole in object B using a Geometry block.
  2. Add a Contact Force block to simulate the interaction between the cable and the hole in B. Add a Constraint block to constrain the cable to pass through the hole in B.
  3. Configure the Contact Force block to act on the cable and the hole in B with zero friction.
  4. Configure the Constraint block to limit the movement of the cable in the X, Y, and Z directions. Then, run the simulation and adjust parameters as needed.

Hi Dhruv,
Thank you for your kind feedback, which is very helpful. However, I still have two questions:
  1. As for your first step, what do you mean is that I create a Cylindrical Solid to replace the hole, so that I can add contact force between "hole" and B, right?
  2. As you mentioned in the second step, I would like to know how to constrain the cable to pass through the hole. As I cannot directly add any constraint to this cable or export the geometry of the cable.
Thanks in advace!!!!
