Week 9-Creation of 1D Connectors Challenge

AIM:
To create mesh of the model with the given quality criteria and connect the components with relevant connectors. 

OBJECTIVE:

• To create mesh with the following quality criteria.
  
  
  
  
• To connect the components with the specified conectors.

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

PROCEDURE:

Meshing:

1. First, import the hood model into HyperWorks.
   
   
2. Now, clean the geometry. Also, to create mesh, open ‘automesh’ and select the component to mesh it. Check for quality criteria and remesh it to achieve the given quality criteria.
   
   
   
   
3. This process is followed for all the components to create mesh.
   
   

Connectors:

1. Turn on Right Rail 2 & Front truss 1 and turn off all the other components. To connect it with Seam-Quad(angled+capped+L), open ‘connectors’ and select ‘seam’, then, choose type, nodes, components and specify spacing and tolerance. After that, click create to get connector elements.
   
   
   
   
2. Similarly, turn on Left Rail 2 & Front truss 1 and turn off all the other components. To connect it with Quad elements, open ‘connectors’ and select ‘seam’, then, choose type, nodes and components and specify spacing and tolerance. After that, click create to get connector elements.
   
   
3. Turn on Front truss 2, Front truss 1 & Right Rail 1 and turn off all the other components. To connect it with Spot weld with 2 layers and 5 mm diameter, open ‘connectors’ and select ‘spot’, then, choose type, nodes, components and also specify tolerance, diameter and layers. After that, click create to get connector elements.
   
   
4. Turn on Front truss 2, Front truss 1 & Left Rail 1 and turn off all the other components. To connect it with Hexa (Adhesive), open ‘connectors’ and select ‘seam’, then, choose type, nodes, components and specify spacing and tolerance. After that, click create to get connector elements.
   
   
   
   
5. Turn on Rear truss 2 & Right Rail 2 and turn off all the other components. To connect it with Bolt connector, open ‘connectors’ and select ‘bolt’, then, choose type, nodes, components and specify tolerance. After that, click create to get bolt connectors. Here, the mesh will get distorted which can be corrected by remeshing.
   
   
   
   
6. The same step above is followed to create bolt connectors on  Rear truss 2 & Left Rail 2.
   
   
   
   
7. Turn on Right Rail 1 & Right Rail 2 and turn off all the other components. To connect it with Spot-weld with Rigid Elements, open ‘connectors’ and select ‘spot’, then, choose type, nodes, components and also specify tolerance, diameter and layers. After that, click create to get connector elements.
   
   
   
   
8. Follow the same step above and select spring as type to create Spot-weld with Spring Elements on Left Rail 1 & Left Rail 2.
   
   
   
   
9. The reinforced plate is connected to Front truss 2 and Front truss 1 using Quad elements. To connect it , open ‘connectors’ and select ‘seam’, then, choose type, nodes and components and specify spacing and tolerance. After that, click create to get connector elements.
