AIM:

Mesh the given geometry. Provided below are the quality parameters that have to follow.

Target Element size - 5 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2 Units
6	Max. Length	8 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	30
10	Max angle Tria	110
10	Tria %	15

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.

SOFTWARE: Hypermesh.

PROCEDURE:

• Import the given model of Frame_Assembly_Welding.
• Check the geometry.
• Mesh the mid surface with given input criteria.

• Create Property and Material
• Material - Steel, Thickness - 2mm
• Assign the Property to the components then the Material will update has itself.

Here Create a connector and Attach the various parts.

1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L).

1D> Connectors> Seam> Nodepath, Component> Type- Seam-Quad(angled+capped+L).

2. Left_Rail_2 & Front_truss_1:- Quad elements.

1D> Connectors> Seam> Nodepath, Component> Type- Quad.

3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 2 Layers and 5 mm Diameter.

1D> Connectors> Spot> Nodepath, Component> Dia- 5mm> with 2 layers.

4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive).

1D> Connectors> Seam> Nodepath, Component> Type- Hexa(Adhesvie)

5. Rear_truss_2 & Right_Rail_2:- Bolt Connector.

6. Rear_truss_2 & Left_Rail_2:- Bolt Connector.

1D> Connector> Bolt> Type- bolt(general).

7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements.

1D> Connector> Sopt> Type- Rigid.

8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements.

1D> Connector> Sopt> Type- Spring.

RESULT:

• Hence generated mesh on every component with quality criteria.
• Required connectors are performed on each component.
