Challenge

Week 9-Creation of 1D Connectors Challenge

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

The procedure with required images:

Step-1:

Any errors in the model geometry are examined. Toggle between 2D Topo and 3D Topo

Step-2:

Set the following criterion for 2D in Preferences-> Criteria file settings.

Step-3: 2D->automesh->surfaces(displayed)->mesh type=mixed->element size=5mm->mesh

Step-4:

After meshing. Then check quality again same as above.

Step-5:

Seam-Quad(Angled +capped+L) for Right Rail 2 and Front truss 1.
type (Seam)-> 1D->connectors->type (Seam)->
Seam-Quad(Angled+capped+L)

To make the seam weld connector, the following alternatives were chosen.

Rear_truss_2 & Right_Rail_2: Bolt Connector

1D->Connectors->Bolt(general)

As the local mesh of the components got distorted, mesh was optimized by using f10->save failed->2D-> elem cleanup

Rear_truss_2 & Left_Rail_2: Bolt Connector

1D->Connector->Bolt-> Bolt(CBAR)

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

1D->Connectors->spot weld

Right_Rail_1 & Right_Rail_2: Spot-weld with Rigid Elements

1D->Connectors->spot (Type= Rigid). This creates RBE2 links

Left_Rail_1 & Left_Rail_2: Spot-weld with Spring Elements(Find these in model)

1D->connectors->Spot->Type=spring. This creates CELAS (elastic) elements.

On the Side of the components was connected using spot weld load transfer type. (Find these in the model)

1D->connectors->Spot->type=weld

1D->Connectors->Seam->Type=weld(Find these in model)
