Week 9-Creation of 1D Connectors Challenge

OBJECTIVE:

 To mesh the given geometry. Provided below are the quality parameters that you have to follow.

Target Element size - 5 Units

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

9. Rest all the component left Join them with suitable connectors

CAD model:

• first we need to mesh the the components individually with target element size=5 by 2D<automesh
• we have reduce the trias by mesh clean up process and check quality of the mesh by check elements as give above quality parameters.and we need to work on up to failed elements to become zero.

CONNECTIONS:

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

• For this we have to hide all components except Right rail2 & Front truss1.
• go to 1D<connectors<seam< Seam-Quad(angled+capped+L)
• select node list on front truss and spacing 5 and select components
• increase the tolerance to 20
• click on create.

2. Left_Rail_2 & Front_truss_1:- Quad elements

• Hide all components except left rail2& front truss 1
• goto 1D<connectors<seam< type quads

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

• hide all components except front truss2
• goto 1D<connectors<spot

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

• hide all components except front truss2,front truss1&leftrail1
• goto 1D<connectors<seam
• increase tolerance 10
• select components
• click on create

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

• hide all elements except left rail1&left rail2
• go to 1D <connectors< spot<change type to spring<select nodes<tolerance=50<diameter=50<select components<click on create.

9.Remaining all joints are connected by seamand spot weld

conclusions:

• meshed the assembly with given target element length and checked quality of elements according to given quality parameters.
• parts have connected with given connectors.
