Week 7 - Creating connection for Rear door

Objective: Create and Apply different PIDs for different components and Perform suitable connections.

Given model: Rear automotive door, with more than 20+ components.

Procedure for Rear Automotive Door

• the component should be topology
• Assign PID for each component
• Connecting the elements at a certain part of the door
• Applying the connection for different types of elements

Topology Perform ANSA topology

As soon as a CAD file is read in ANSA automatically Topology is performed Between PIDs: perform topology between different CAD layers Between parts perform topology between different parts.

Respect file topology: respect the topology of the file Clean Geometry: perform automatic geometry cleanup in addition to topology

Assign PID for each component

• The user can also create a new PID if it does not already exist in the list.
• Activate the Set PID function, select the Macros, and confirm with the middle mouse button.
• The Properties window appears. Press the New>PSHELL (for NASTRAN) button to create a new property.
• A new Shell Property card opens. Type in the required name and values and press OK.

Examine the FE model to see the possible connection

There are 4 types of connection required, those are

1. Seam Weld
2. Bolt
3. Window damper (Window liner)
4. Revit joint.

• Most Automotive parts are permanently joined with the help of the seam welding method.
• Again there are two sub category of weld, Overlap and T- Weld.
• In overlap weld, both the plates are parallel, whereas in T-weld, plates are perpendicular.

Bolt join can be done either manually or automatically ffs

Manually:

• To perform manually, select RBE2 element (Nastran>Elements>RBE2)sr
• Select many Nodes, if only the periphery nodes are only required then select the individual nodes.
• then proceed next, apply a degree of freedom if required, and set PID for the bolt joint

see the connection in the transparency mode

Window damper (Window liner)

• To provide the window liner create the curve through FE Mesh>perimeter>feat2Curve
• Select the curve and convert it into a seam line (Assembly tab>Convert>Curve>Spotline)
• Once the curve is converted into a seam line, the curve turns into a bright pink curve.
• Open Connection Manager and select the spotline line.
• Select P1 and P2, and space (S).
• Select the FE rep Type as "RBE3-CBUSH-RBE3"
• Enter the Search distance and set CBUSH PID.
• Do, apply, and realize.

conclusion

To follow the above procedures step by step to achieve the other parts of the car door components
