Week 9-Challenge

Objective: To create connector and attach the various parts of the given model.

Procedure:

1. First imported the model file using the Import Geometry option under the Import.

2. Switched to topo mode to check for solids. As there are no solids,displayed components are mid surfaces.

3. Now selected the mid surfaces one by one to work on them.
4. Then meshed them with element size as 5mm using the automesh option in the 2D panel.The final meshed surfaces are shown below.

5. Now to create connectors in order to attach the various surfaces of the model.

• Then connected the component using the Bolt Connectorunder the Connectors command in the 2D panel.

• The required connected meshed surfaces are shown below.

Step 6: To connect Rear_truss_2 & Left_Rail_2 using Bolt Connector

• Enabled the meshed parts of required mid surfaces to work on them.

 

• Then connected the component using the Bolt Connectorunder the Connectors command in the 2D panel.

• The required connected meshed surfaces are shown below.

• After this adjusted the distorted meshed elements by remeshing the elements.

Step 7: To connect Right_Rail_1 & Right_Rail_2 using Spot-weld with Rigid Elements 

• Enabled the meshed parts of required mid surfaces to work on them.

 

• Then connected the component using the Spot-weld with Rigid Elementsunder the Connectors command in the 2D panel.
