Week 9-Challenge

Aim:

To create mesh and connect the components with suitable connectors.

Methodology:

• To create a good quality mesh.
• Connect the components with suitable connectors.

Introduction:

A truss is an assembly of beams or other elements that creates rigid structures.

Procedure:

• Import the model

Figure-1(model import)

• Clean up the geometry.
• Mesh the components by “automesh” option or click F12 function key.

Figure-2(Meshed model)

Seam Quad:

• Select the right rail 2 and front truss 1 mesh geometry.
• Go to 2D- connectors.
• Click on “seam” option and select “seam-quad(angled+clapped+L)”.
• Select the nodes, components and allot spacing values.
• Tick on “retain nodes”
• Click on “Create”.

Quad:

• Select the left rail 2 and front truss 1 mesh geometry.
• Go to 2D- connectors.
• Click on “seam” option and select “quad”
• Select the nodes, components and allot spacing values.
• Tick on “retain nodes”.
• Click on “Create”.

Spot weld:

• Select the front truss 1,2 and right rail 1 mesh geometry.
• Go to 2D- connectors.
• Click on “spot” option and select type as “weld”.
• Select the nodes, components and allot spacing values.
• Select the no.of layers as 3 and set diameter as 5mm.
• Click on “Create”.

Hexa :

• Select the front truss 1,2 and left rail 1 mesh geometry.
• Go to 2D- connectors.
• Click on “spot” option and select type as “hexa(adhesives)”.
• Select the nodes, components and allot spacing values.
• Click on “Create”.

Bolt:

• Select the rear truss 2,left & right rail 2 mesh geometry.
• Go to 2D- connectors.
• Click on “bolt”option and select type as “bolt(general)”.
• Select the node, components and allot spacing values.
• Select the “create hole,if none”.
• Click on “Create”.

Figure-7(bolt connection)

Spot weld with rigid:

• Select the right rail 1 & 2 mesh geometry.
• Go to 2D- connectors.
• Click on “spot” option and select type as “rigid”.
• Select the node, components and allot spacing values.
• Click on “Create”.

Figure-8(spot weld with rigid)

Spot weld with spring:

• Select the left rail 1 & 2 mesh geometry.
• Go to 2D- connectors.
• Click on “spot” option and select type as “springs”.
• Select the node, components and allot spacing values.
• Click on “Create”.

• All other connections are done with suitable connections like rigid etc

Figure-10 (rbe2 connections)

• All the connections can be edit in connectors bar.
• Click on view-Hypermesh and select connector.
• A menu bar will be pop up.

Learning outcome:
Learnt how to get different types of connections like

1. Bolt
2. Seam
3. Spot
4. Area etc

Result:

The model is mesh and connected with suitable and given connnection types.
