Week 9-Creation of 1D Connectors Challenge

Aim:- Creation of 1D Connectors

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 3 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

STEP-1

• Imort the Frame_assembly_welding.hm to hypermesh under optistruct profile.

STEP -2

• 2D automesh the component with 5mm as target element size as the midsurface is available.

STEP-3 SEAM WELD CONNECTION

• Hide all the component except right rail 2 and front truss 1.
• Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)
• Select the node list on front truss and components to connect with remesh option.
• Increase tolerance value to 10 and click create and remesh the area for proper mesh flow.

STEP-4 QUAD ELEMENTS

• Hide all the component except left rail 2 and front truss 1.
• 1D connectors> Seam and typr as QUADS.
• Create a property for quad elements and assign.
• Select the node list on front truss and components to connect with remesh option.
• Increase tolerence the area for proper mesh flow.

STEP-5 SPOT WELD

• Hide all components except Front truss 1, front truss 2 and right rail 1.
• 1D < connectors < spot type as weld diameter as 5mm.
• Select the nodes to spot weld and components to connect with 3 layers
• Create a property for spot weld and assign click create with 20 tolerance.

STEP 6 HEXA ADHESIVE CONNECTOR

• Hide all components except front truss 2, front truss 1 and left rail 1
• 1D < connectors < seam type as Hexa Adhesive.
• Increase tolerance to 50, select nodes in one component and select components to connect create.

STEP-7 BOLT CONNECTOR

• Hide the component except Rear truss 2 and Right rail 2
• 1D <bolt type as bolt general.
• Select the nodes and components to connect.
• Increase tolerance to 50 and select create bolt if necessary.

STEP-8 SPOT WELD WITH RIGIDS

• Hide all components except as right rail 1 and right rail 2
• 1D > connector >spot type as rigids select nodes to connect assign property.
• Select components to connect after incresing tolerance to 20 and create.

STEP-9 SPOT WELD WITH SPRINGS

• Hide all components except left rail 1 and left rail 2.
• 1D >cnnectors<spot type as spring select nodes to connect assign property
• Select components to connect after increasing tolerance to 50 and create.

• Remaining components are connected using seam weld spot weld by following above steps.

RESULT:-

• The frame assembly is meshed.
• The connections are represented as specified.
• Remaining components if frame assembly are connected by means of seam and spot welding.
