Week 9-Creation of 1D Connectors Challenge

Week 9 - Creation of 1D Connectors Challenge

AIM:

Meshing of the given geometry. Provided below are the quality parameters that you have to follow.

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. Importing the model:

• At first we need to Import the Model File>>Import>>Model>>Select the model>>Import.

2. 2D Meshing:

• To generate mesh go to 2D>>automesh>>Element size=5>>mesh type Mixed>>Select the surface>>mesh.
• To get a proper flow edit the mesh by selecting the elements and click on mesh.
• If any element is failing for Quality criteriia Then we can use the cleanup tools in qualityindex and we can use translate tool on some areas.

3. Creating Connectors:
4. Seam Weld connections :

• Hide all the components expect Right Rail 2 & Front Truss 1.
• 2D<Connectors<Seam<Type=Seam-Quad(angle + capped + L).
• Select the node list and give Spacing value as 5.
• Select the components and give tolerance value as 10 click create.
• Remesh the required areas for proper mesh flow.

2. Quad elements:

• Hide all the components expect Left Rail 2 & Front Truss 1
• 2D<Connectors<Seam<Type=Quad.
• Select the node list and give Spacing value as 5. .
• Select the components and give tolerance value as 10 click create.
• Remesh the required areas for proper mesh flow.

3. Spot Weld:

• Hide all the components expect Front Truss 2 & Front Truss 1 & Right Rail 1.
• 2D<Connectors<Spot<Type=Weld.
• Select the node list and give Spacing value as 5.
• Select the components and give tolerance value as 20 click create.
• Select the number of layers as 2 and diameter as 5.
• Remesh the required areas for proper mesh flow.

4. Hexa (Adhesive):

• Hide all the components expect Front Truss 2 & Front Truss 1 & Left Rail 1.
• 2D<Connectors<Seam<Type=Hexa (Adhesive).
• Select the node list and give Spacing value as 5.
• Select the components and give tolerance value as 20 click create.
• Remesh the required areas for proper mesh flow.

5. Bolt Connector:

• Hide all the components expect Right Rail 2 & Rear Truss 2.
• 2D<Connectors<bolt<Type=bolt(general).
• Select the node list.
• Select the components and give tolerance value as 50 click create.
• Remesh the required areas for proper mesh flow.

6. Similar steps for bolt connector repeat the same for Rear Truss 2 & Left Rail 2
7. Spot Weld with Rigid elements:

• Hide all the components expect Right Rail 1 & Right Rail 2.
• 2D<Connectors<Spot<Type=Rigid.
• Select the node list and give Spacing value as 5.
• Select the components and give tolerance value as 20 click create.
• Remesh the required areas for proper mesh flow.

8. Spot Weld with Spring elements:

• Hide all the components expect Left Rail 1 & Left Rail 2.
• 2D<Connectors<Spot<Type=Spring.
• Select the node list and give Spacing value as 5.
• Select the components and give tolerance value as 20 click create.
• Remesh the required areas for proper mesh flow.

9. Remaining components are connected using Spot Weld and Seam Welds by following the above mentioned steps.

CONCLUSION:

Hence every components have been meshed and required connections have be defined and sucessfully realized. Finally the entire connections and meshed components are shown below.
