IV. Constrain the Manifold (LockDOF_Manifold and Clamp_Manifold_->_Engine)
The Manifold is located to Engine with rigid body moves; pattern move floats the Manifold holes onto Engine bolts.
4.1 Add a LockDOF move for all five holes in the Manifold. The floated holes will be locked in X-dir and Y-dir.
4.1.1 Select the
LockDOF icon and chose the ExhaustAsm product as parent part.
4.1.2 Name the move "LockDOF_Manifold" with a description of "LockDOF Manifold holes in x, y-dir"
4.1.3 Click on the [ClickToAdd] button in the Positioning Pts section and select points B_H1_Man-Eng, H2_Man-Eng, H3_Man-Eng, H4_Man-Eng and C_H5_Man-Eng on the Manifold part from the Navigation Tree or from the Graph window.
4.1.4 In the XYZ section check the X and Y boxes for all points to constrain them in X and Y directions.
4.1.5 Rx, Ry, Rz are rotational degrees of freedom. Leave the rotations free.
4.1.6 The completed dialog box should appear as below:
4.1.7 Click [OK] to close the LockDOF move dialog box.
4.1.8 Save the model.
4.2 Add a Clamp move for the three surface points in the Manifold. Points A1_Base, A2_Base and A3_Base will be clamped with Infinite force to the Engine using Target Associate direction and Hard (All DOF) joining type.
4.2.1 Select the
Clamp icon and choose the ExhaustAsm product as parent part.
4.2.2 Name the move "Clamp_Manifold_->_Engine" with a description of "Clamp Manifold to Engine, hard clamp, target plane,infinite force".
4.2.3 Click on the [ClickToAdd] button text in the Clamping Object Pts section and select points A1_Man, A2_Man and A3_Man for the Manifold in the Navigation Tree or from the Graph window.
4.2.4 Click on the [ClickToAdd] button text in the Clamping Target Pts section and select points A1_Man, A2_Man and A3_Man for the Engine_Body_Ref-Exhaust in the Navigation Tree or from the Graph window.
4.2.5 Activate the Smoothing to deform the whole part.
Results:
The nominal values of the measurements after constraining the Manifold remain unchanged.
