Detect object overlapping in Simscape Multibody
显示 更早的评论
Hello community,
I'm currently working on a project where I'm trying to support my development with Simscape Multibody. The project involves a system consisting of multiple cylinders that are attached to rigid rods (modelled as solids). To ensure flawless motion of the system, I want to build a Simscape model to detect potential collisions in the multibody system.
Ideally, I want to actuate all the cylinders automated to reach all possible positions and automatically detect where objects overlap (and export this information to verify it in my CAD-software).
Normally in SimScape, when objects are overlapping (e.g. a cylinder piston "crashing" into its housing), nothing happens as these end stops have to be specified in the joint properties. Is there a way to detect overlapping objects without letting them collide (and bring the motion to a stop) as it would be the case when you use the "spatial contact force" block?
Thanks in advance.

Hi Lukas
You can use the Spacial Contact Force block despite it. You just have to set the friction force to None and the Normal Force to Provided by Input and then input nothing. You can recognize the contact with the sensing function, especially the contact frame could be interesting for you.
I hope it will work for you.
