Dynamic Simulation – Part 1


So let’s look a little more at the Dynamic Simulation environment. (DS)

When entering DS you go to your Environments Tab and begin Dynamic Simulation.

Dynamic Simulation 01

The ribbon changes to reflect the tools available for DS.

Dynamic Simulation 02

The browser also changes to reflect that you are in the DS environment.

Dynamic Simulation 03

You can see that you have the Grounded folder which contains parts or assemblies that cannot move and the Mobile Groups folder which contains parts and assemblies that can move. If you create a joint (make 2 parts move with relation to each other) and those parts were in the Grounded folder, they will automatically be placed in the Mobile Groups folder.

You also have joints folders created where the appropriate joint will be placed. You have the following joints.

  • Standard Joints
  • Rolling Joints
  • Sliding Joints
  • 2D Sliding Joints
  • Force Joints

Next to each joint you will also see which components are involved with that particular joint.

If you used assembly constraints you would probably want to automatically convert the constraints that you used to create your joints. This is automatically selected in Inventor 2016 and can be changed under the Simulation Settings.

Dynamic Simulation 04

If you deselect this the software asks if you would like to keep the joints that were automatically created or if you would like to delete them and start from scratch.

Dynamic Simulation 05

If you select no this happens.

Dynamic Simulation 06

You will notice that there are now no mobile components in this assembly and all components have been grounded. There are no more joints, but we still have gravity.

To add the joints automatically to your Dynamic Simulation you can once again go to your settings, make sure that the tick box next to ‘automatically convert constraints to standard joints’ is ticked and you have your joints back again.
