Week 12-Creation of 1D Connectors Challenge

Aim/Objective :
To create connection of 1D connectors
Mesh the component as per quality criteria

Quality criteria :

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

11 Tria % 15

Procedure

Steps :
Import the midsurface in hypermesh for meshing the component
Add the quality criteria and mesh the component
Rebuild the failing areas clear the quality criteria
1 Seam quad is created by 1D connector seam nodes by path
spacing weld path given nodes selected and both component to created
2 Quad use the 2d connectors seam select type quad if required add tolerance values
select nodes then both the component for quads element
3) spot weld use 2D connectors spot click the nodes enter tolerance and diameter
select nodes on elements and select both componenet create spot weld
4)Hexa or adhesive can be created by 1D elements connectors area type adhesive
Select the elements and the component by giving tolerance value for hexa creation
5 Under 2D connectors bolt was selected type general bolt
selected the nodes and component for bolt creation
6 The above 5 step was used as same for rear truss 2 left rail 2
7 under 2d connectors spot weld type rigid was selected
Selected the nodes and component weld was created
8 under 2d connectors spot weld type spring elements was selected
Selected the nodes and component weld was created
9 For the remaining component spot weld rigid and spring created file saved

Learning outcomes :
Learned different use of bolt and weld

To create joints like hexa spot seam quad and bolt
These bolt and weld joints differ from industry

Result :
Thus the bolt weld connection was created and the file is attached for reference
