Construct Moving Assemblies; Retain Degrees Of Freedom - Autodesk 466B1-05A761-1304 - AutoCAD Inventor Simulation Suite 2010 Getting Started Manual

Construct Moving
Assemblies
To simulate the dynamic motion in an assembly, define mechanical joints between the parts.
This chapter provides basic workflows for constructing joints.

Retain Degrees of Freedom

In some cases, it may be appropriate that certain parts move as a rigid body and
a joint is not required. As far as the movement of these parts is concerned, the
welded body functions like a subassembly moving in a constraint chain within
a parent assembly. Similarly, at other times, components making up a welded
group will need degrees of freedom for movement within the simulation. Such
is the case with the welded group in the Saw model.
Create a 2D contact
1 In the browser, expand Mobile Groups.
2 Right-click the Follower Roller and click Retain DOF. This allows the roller
to retain its motion characteristics.
3 In the graphics region, click and drag the Follower away from the Cam
crank assembly.
4 On the ribbon, click Dynamic Simulation tab
Joint and from the list, select 2D Contact.
5 Select the Cam profile edge (1).
