Week 9-Creation of 1D Connectors Challenge

AIM :

To mesh the given Component with a Mesh size of 5mm and create connector and attach the various parts of the given model with the following types of 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

TOOLS REQUIRED :

• HyperMesh

PROCEDURE :

• The given geometry model frame_assembly_welding.hm is opened in HyperMesh using File -> Open -> Model option.

Model

• The given model is meshed with element size 5 mm.

Meshed model

• There are mainly three types of connections used in this model - Seam weld, Spot weld and Bolt connection.
• Right_Rail_2 & Front_truss_1 are connected using Seam-Quad(angled+capped+L) seam weld. This is done by using 1D -> connectors -> seam tool selecting type of weld as Seam-Quad(angled+capped+L).

• Left_Rail_2 & Front_truss_1 are connected using Quad seam weld. This is done by using 1D -> connectors -> seam tool selecting type of weld as quad.

• Front_truss_2, Front_truss_1 & Right_Rail_1 are connected using Spot weld with 3 Layers and 5 mm spot diameter. This is done by using 1D -> connectors -> spot tool selecting type of weld as weld.

• Front_truss_2, Front_truss_1 & Left_Rail_1 are connected using Hexa (Adhesive) seam weld. This is done by using 1D -> connectors -> seam tool selecting type of weld as hexa(adhesive).

• Rear_truss_2 & Right_Rail_2 are connected using Bolt connector. This is done by using 1D -> connectors -> bolt tool selecting type of bolt as bolt(general).

• Rear_truss_2 & Left_Rail_2 are connected using Bolt connector. This is done by using 1D -> connectors -> bolt tool selecting type of bolt as bolt(general).

• Right_Rail_1 & Right_Rail_2 are connected using Spot weld with Rigid Elements. This is done by using 1D -> connectors -> spot tool selecting type of weld as rigid.

• Left_Rail_1 & Left_Rail_2 are connected using Spot weld with Spring Elements. This is done by using 1D -> connectors -> spot tool selecting type of weld as spring.

• Rest all the components are connected by spot weld connection.

RESULTS :

• The given model is meshed and connected using seam, spot and bolt connections and the final connected model is shown below.

CONCLUSION :

The given model is connected as per the given conditions and the final model is attached with this report.
