THEORY: Geometric entities that define connections between other entities
• Used for welding, bolts, adhesives, etc.
• Link geometry or FE entities
• Can be “realized” into FE representations of welds, etc. for any supported solver
• rigids, CWELDs, MAT100s, ACMs, etc.
Connectors allow for easy and rapid:
• Creation of FE welds, bolts, adhesives, etc.
MODEL:
PROCEDURE:
STEP1: Import the model into the graphical area.
STEP2: Perform geometry cleanup on the component if necessary.
STEP3: Mesh each component with given element size separately and make sure the mesh flow is proper.
STEP4: Make sure it follows the given quality criteria.
STEP5: Then we are ready for connecting them with different connectors.
1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-seam
STEP3: Select the nodes of one component by path and select both components
STEP4: Set the tolerance as 10units and spacing as 5 units.
STEP5:Select the weld type-Seam-Quad(angled+capped+L)
STEP6: Specify weld angle as 60 or 45 degrees and click create.
2. Left_Rail_2 & Front_truss_1:- Quad elements
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-seam
STEP3: Select the nodes of one component by path and select both components
STEP4: Set the tolerance as 10units and spacing as 5 units.
STEP5:Select the weld type-Quad
STEP6: Specify weld angle as 60 or 45 degrees and click create.
3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 2 Layers and 5 mm Diameter
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-spot
STEP3: Select the nodes of one component by path and selectall three components
STEP4: Set the tolerance as 10units and diameter as 5mm.
STEP5:Select the type-weld and layer is set as three.
4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive)
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-seam
STEP3: Select th nodes of one component by path and select both(top and middle) components
STEP4: Set the tolerance as 10units and spacing as 5 units.
STEP5:Select the weld type-hexa-adhesive
STEP6: Specify strips,coats and width as 1unit and click create
STEP7: Similarly select middle and bottom component and follow the same procedure.
5. Rear_truss_2 & Right_Rail_2:- Bolt Connector
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-bolt
STEP3: Specify the bolt location and select two single nodes at a certain distance.
STEP4: Set the tolerance as 10units.
STEP5:Select the weld type-bolt(general)
STEP6: Select the option to create a hole
6. Rear_truss_2 & Left_Rail_2:- Bolt Connector
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-bolt
STEP3: Specify the bolt location and select two single nodes at a certain distance.
STEP4: Set the tolerance as 10units.
STEP5:Select the weld type-bolt(CBAR)
STEP6: Select the option to create a hole
7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-spot-type-rigid
STEP3: Select the nodes of one component by path and select all components
STEP4: Set the tolerance as 10units.
STEP6: Specify the diameter and number of layers as 2 and click create.
8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements
STEP1: Hide all components except required.
STEP2:Go to 2d-connectors-spot-type-spring
STEP3: Select the nodes of one component by path and select all components
STEP4: Set the tolerance as 10units.
STEP6: Specify the diameter and number of layers as 2 and click create.
CONCLUSION: All the connectors were successfully established and realised.
*Rest of the components were connected with suitable connectors.
*Elements failed before the connections were made was zero and after connectors were made some elements were failing.
