Week 9-Creation of 1D Connectors Challenge

OBJECTIVE:

To mesh the frame assembly and create connectors and attach various partof given model.

PROCEDURE :

Import the frame_assembly_welding.hm model to hypermesh under optistruct profile.

2D > Automesh the component with 5mm as target elemet size as the midsurface is already available.

CONNECTORS:

1. SEAM WELD CONNECTION

Hide all components except right rail 2 and front truss 1.1D > connectors > seam type as seam-quad(angled+cappled+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.

2. QUAD ELEMETS

Hide all components except left rail 2 and front truss 1.

1D > Connectors > Seam and type 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 tolerance value to 10 and Click create and remesh the area for proper mesh flow.

3. SPOT WELD

Hide all components except Front truss 2 , Front truss 1 and right rail 1.2D > 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 tolerance 20.

4. HEXA ADHESIVE CONNECTOR

Hide all components except Front_truss_2, Front_truss_1 & Left_Rail_1 .2D > connectors > seam type as Hexa (adhesive).

Increase tolerance to 50 , select nodes in one component and select components to connect.Select create.

5. BOLT CONNECTOR

Hide the components except Rear_truss_2 & Right_Rail_2.21D > Bolt type as Bolt (general).

Select the nodes and components to connect. Increase tolerance to 50 and select create bolt if necessary.

Follow the same steps for Rear_truss_2 & Left_Rail_2.

6. SPOT WELD WITH RIGIDS

Hide allo components except Right_Rail_1 & Right_Rail_2. 2D > Connectors > spot type as rigids select nodes to connect. Assign property.

Select components to connect after increasing tolerance to 50 and create.

7. SPOT WELD WITH SPRINGS

Hide all components except Left_Rail_1 & Left_Rail_2.2D > Connectors > spot type as springs 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, Spring and othe connectors by following above stepsin the model.

Remesh all the component for proper mesh flow.

CONCLUSION:

All the parts of the model is connected using connectors and meshed for proper flow and checked for element quality by given quality parameters
