Compressed Earth Bricks - CETA RAM Machine - Stuck in Animation / Motion Study Workflow

[leonard.caspers]

Dear Community,

I am currently working on the design of a CETA RAM Machine, which is made to compress earth mixtures into bricks. I have come quite a long way in the project and I now want to simulate the movement of the machine to validate my design and to be able to present the machine to my team and others.

The motion of the machine is quite complex, because the joints themselves don´t always stay in the same position. There are also some movements, which should require contact sets, because some components are used as levers over other components.

Here you can see an example of the machine / movement design I am trying to achieve:

I think that I have worked out all the important joints of the machine, yet the Motion Study feature doesn´t really work for me. Also my contact sets don´t seem to work properly. I would really appreciate any tips to achieve the desired motion, shown in the video...

Thanks in Advance

Leo

I would start this design completely from scratch! 

There are 85 warnings (yellow icons in the timeline) and several errors (red icons).

Before proceeding, every single one of those should be fixed! 

Once that's done, we can talk about joints and animation.

As you might have already figured out, the animation workspace does not honor joints.

Also, your design workflow contains a number of not recommended techniques. In a timeline based design, mechanical design like this, I would not expect to see a body move operation (cross hair) or a capture position feature.

Once you get the modeling issues sorted (as indicated by @TrippyLighting ) (Ctrl b on Windows, CMD b on Mac) I would take the assembly over into Autodesk Inventor Professional >Dynamic Simulation Environment.

There are a plethora of Joint types that Fusion simply doesn't have (and functionality associated with those Joints).
