Mechanical Movement Playback - Help

[lucasliraAU]

Hello friends!

I am having some difficulties in implementing the joint points for the implementation of this mechanical movement.

Check out the video below:

 I am leaving photos and the Fusion360 file from my complete structural assembly I am needing help to deploy this move.

 

I ask for help to implement these movements if possible a screencast so that you can learn the ideal positioning for the application!

Thanks for your attention!

Hi @lucasliraAU,

That is definitely a complex assembly and one of the things we want to do is make the joint constraints as simple as possible.

The first thing I recommend off the bat is to create a rigid group for all the components that don't move with respect to each other. Creating a group, instead of multiple joints will make it much easier on you, as well as for Fusion to compute the motion.

Start there, and then work through the revolute joints for the motion.

I'm downloading your file now to take a look as well.

Hello! @sachlene.singh, 

First of all I would like to thank you for your attention on this project!

I'm trying to work on your guidelines for my model, I'm trying to create the rigid groups for each section yet I have not achieved any results I believe I'm missing out on some joining point or something to mechanical relationships.

some images...

If you get some results in screencast would appreciate, to understand the execution of the work.

@lucasliraAU,

I'm going to have to go through the model one component at a time and this might take a while.

What I will be doing is going back to the beginning of the timeline, and start creating joints as the components come in, rather than at the end. What this does is ensures that the components placed in the assembly are correctly constrained before the next component is placed in.

I recommend you do the same with assemblies as complex as this.

Still working on this,

You were very very close! I added a couple joints and its working the way you were expecting it to.

You had the correct positioning of the joints you have already created. nice work!

1. Ground a component before you start creating joints. This would be a component that doesn't move, and that all other components move about. I grounded the first component you put in.

2. I added two revolute joints. the ones shown below.

The motion is 90% there if not all done. Try dragging one of the legs left and right to understand what else needs to be constrained with a joint.

I hope this helps. Here is the model thus far: http://a360.co/2kYArDh

Hello again 🙂

I will download the file to understand the move, return as soon as I can

Thank you very much for your commitment to this work, I am learning from this.

Best regards;

I'm having some kind of problem opening the file on my Fusion 360,

could share a folder with my email file for sharing would - lucas.teamchallengers@gmail.com

Thank you for your willingness!

The file still has some kind of problem that I can not open it!

I have been able to develop the movements that I need thanks to your guidance.

Thanks for your help!

Oh no! I'm sorry you're not able to open it. One thing to check is to make sure your version of Fusion has the latest update installed. I'm running version 2.0.3620.

Anyways, I'm glad you got it to work. You just needed a couple more revolute joints.
