Create connector and Attach the various parts of the given model

1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)

2. Left_Rail_2 & Front_truss_1:- Quad elements

3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 2 Layers and 5 mm Diameter

4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive)

5. Rear_truss_2 & Right_Rail_2:- Bolt Connector

6. Rear_truss_2 & Left_Rail_2:- Bolt Connector

7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements

8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements

9. Rest all the component left Join them with suitable connectors

Procedure:

1) Import the Geometry.

2) Mesh the model as per the given quality parameters.

3) Create material ( steel ) and property (Card image: PSHELL)

1D Connectors:

1) Seam-Quad(angled+capped+L)

(Right_Rail_2 & Front_truss_1)

• Go to 1D>CONNECTORS>SEAM>Seam-Quad(angled+capped+L)
• Select the nodes( by path) on one of the components.
• specify spacing and tolerance
• select the components and click create.

2)Quad elements

(Left_Rail_2 & Front_truss_1)

• Go to 1D>CONNECTORS>SEAM>Quad
• Select the nodes( by path) on one of the components.
• specify spacing and tolerance
• select the components and click create.

3)Spot weld with 2 Layers and 5 mm Diameter

( Front_truss_2, Front_truss_1 & Right_Rail_1)

• Go to 2D>CONNECTORS>SPOT>WELD
• Select the nodes( by path) on one of the components.
• specify diameter, the number of layers, and tolerance
• select the components and click create.

4)Hexa (Adhesive)

( Front_truss_2, Front_truss_1 & Left_Rail_1)

• Go to 1D>CONNECTORS>SEAM>HEXA
• Select the nodes( by path) on one of the components.
• specify the strips coats width and tolerance
• select the components and click create.

5,6) Bolt Connector

(Rear_truss_2 & Left_Rail_2)

• Go to 1D>CONNECTORS>bolt
• Select the nodes( by path) on one of the components.
• specify the tolerance
• select the components and click create.

7)Spot-weld with Rigid Elements

(Right_Rail_1 & Right_Rail_2)

• Go to 2D>CONNECTORS>SPOT>RIGID
• Select the nodes( by path) on one of the components.
• specify diameter, the number of layers, and tolerance
• select the components and click create.

8) Spot-weld with Spring Elements

(Left_Rail_1 & Left_Rail_2)

Similarly as per the previous case.

9)Others

Area (Adhesive)

Seam Quad

Conclusion

All the required connections have been realized successfully.
