What kind of mate would I need to solve this?

Benedict Kent Oct 9, 2014 7:31 AM

Hello,

I was wondering if you could help me with a solution to a problem. I have an assembly where a box when it sits down on a lever causes the lever to move and when the box is released the lever falls back.

In short I need a collision mate where the lever moves only when the box touches it and when weight is taken off it reverts to original position. I'm using Solidworks 2013 professional.

Can you attach your assembly here?

  Hi, I'm afraid due to what I'm working on I don't want to upload anything IP concerns.
  Basically I'm looking for a way I can move the box up and down and the lever only moves when the box hits it. I'm beginning to think SW doesn't have the capability from digging around the help files.

    Are you using Motion Study?
    Can you create a simplified assembly that exhibits the same desired behavior without revealing any IP issues?
    
    I would expect my students to create the equivalent of a very simple "3D - Free Body Diagram" as a proof of concept before modeling the "real world" geometry.
    
    What book are you using to learn SolidWorks Motion Studies?

      Hi,
      
      Here is a simple assembly of what I'm trying to achieve. The concept for the project I'm working on is sound, just trying to figure the mates so I can animate it so my bosses can see.
      Until recently we haven't really needed to get into complicated mating arrangements so I'm learing motion study by doing.
      
      Thanks for all assistance.

        I would say if you're just trying to show a "boss" (or other non-technical person) just use the "move" command within the assembly and either check "Collision Detection" and/or "Physical Dynamics" to simulate the real-world contact scenarios. Or as the others say, you can run a simple Motion Study, which I believe runs the same collision engine, but allows more control with time as a variable...
