Drive and Driven Assembly Simulation

[roboram]

Im currently designing a arm assembly to catch a specific surface.

I use a wedge/cam to move the arms and the cam profile has to drive the arms left and right to be vertical as shown in first pic.When the cam moves down the arms should automatically come down due to gravity.

Im struggling to get this profile created since im unable to simulate the movement of the camsurface to drive the arm.

What constraint i need to use this make sure it works?Also if i remove the same completely as shown in pic 3 how to see the arms falls down due to gravity?

Much appreciated

You will need to become familiar with Environments>Dynamic Simulation.

You will need at least sketches of the parts (do not need full solid geometry).

Attach your *.ipt files here for the parts for next step.

Thanks for the update.

Pls find attached parts.Still primitive,but just wanted to make the profile based on the travel up and down.

That could be moving better. I've tried Contact set in Assembly environment, and 3D Contact in DS.

Both are showing issues.

In Assembly, you can see movement by moving the Driveme constraint. It's not bad, but if Angle:1 or Angle:3 is unsuppressed, movement doesn't run through

In DS, 3DContact is running empty at the end of the move.

Thank you so much for your idea.It worked.

Currently i had to change the design based on the drive end.

Attched is the 2d sketch and the 3d model files.Instead of the cam moving the lever profile i have made the profile that touches and activates the lever to rotate and lock it in place.

Even though i have created contact set,still this animation deosnt work.What is the error in the assembly?

Please help

Thanks again

Hmm. Looking at your DWG screenshot, I don't see, how the hydraulic cylinder is driviing the angular position of the grippers.

[roboram]

The Hydraulic Cylinder moves up and down and a shaft that is connected to the cylinders across has this lever mounted.

When the cylinder moves up and so is the lever and it goes and hits on the profile of the lever arm and flips around to hold the object.

I want to simulate when the lever profile drives the lever to rotate around and hold the angle box section.

Pls refer to my model files.

Much appreciated.
