Week 9-Creation of 1D Connectors Challenge
OBJECTIVE:
Creating the various connectors from 1D, 2D or 3D as suitable connectors such as spot, bold, seam. and area respectively and attach the various parts with these connectors.
PROCEDURE:
The model frame assembly has 9 parts such as front truss1, front truss 2, right plate, right rail 1, right rail 2, left rail 1, left rail 2, rear truss 1, rear truss 2, and they have attached with different types of connectors to different parts respectively as mentioned below in the table.
The frame assembly was on the same collectors which were shifted to different collectors in the organize. And before adding connectors all parts are given materials: steel and property : thickness 1 mm and it is assigned to each individual part.
| Sr No | Connected Parts | Connectors | Type |
| 1 | Right_Rail_2 & Front_truss_1 | Seam | Quad(angled+capped+L) |
| 2 | Left_Rail_2 & Front_truss_1 | Seam | Quad elements |
| 3 | Front_truss_2 Front_truss 1 & Right_Rail_1 | Spot | Weld |
| 4 | Front_truss_2 Front_truss 1 & Left_Rail_1 | Seam | Hexa(Adhesive) |
| 5 | Rear_truss_2 & Right_Rail_2 | Bolt | Bolt(general) |
| 6 | Rear_truss_2 & Left_Rail_2 | Bolt | CBAR |
| 7 | Right_Rail_1 & Right_Rail_2 | Spot | Weld(Right element) |
| 8 | Left_Rail_1 & Left_Rail_2 | Spot | Weld(Spring element) |
| 9 | Right_Rail_1 & Rear_truss_2 | Area | Rod |
| 10 | Left_Rail_1 & Rear_truss_2 | Spot | Spring |
| 11 | Refin plate & Front_truss_2 | Spot | Bar 2 |
| 12 | Front_truss_2 & Right_Rail_1 | Spot | Rigid link |
| 13 | Front_truss_2 & Left_Rail_1 | Bolt | Bold(Hinge) |
Right_Rail_2 & Front_truss_1
Connecting Right_Rail_2 & Front_truss_1 with seam connectors types given as quad(angled+capped+L)
Command : (1D+Seam+type:seam quad (angled+capped+L) + Tolerance: 10 + Weld angle: 60, cap angle: 45, + run off angle: 10 + Create)
While connecting connectors on both parts there are some distorted elements that are fixed manually in the quality index by placing nodes and moving trias or remesh them by 4mm element size.
Left_Rail_2 & Front_truss_1
After adding connectors no elements were distorted.
Command : (1D+Seam+Spacing4 + Type: seam quad+ Tolerance: 10 + Create)
Front_truss_2 Front_truss 1 & Right_Rail_1
Command : (1D+Spot+ Type: weld +No of layers: 3, Diameter: 5mm, Tolerance: 10+ Create)
Front_truss_2 Front_truss 1 & Left_Rail_1
Command : (1D+Spot+Spacing4 + Type: Hexa(adhesive)+ Strips: 01+ Coats: 01+ Tolerance: 10+ Create)
Rear_truss_2 & Right_Rail_2
Creating the connectors there are some elements which are distorted because of the hole created and it is fixed by remesh and quality index.
Command: (1D Bolt +Type Bolt(general), no of layers: 2, Tolerance: 10, create hole if none + create)
Rear_truss_2 & Left_Rail_2
Command: (1D+Bolt+ Type: Bolt (CBAR) + No of layers: 2 + Tolerance: 10 + create hole if none + create)
Right_Rail_1 & Right_Rail_2
Command: (1D + Type: rigid + No of layers: total 2+ Tolerance: 10 : Diameter: 1 + Create)

Right_Rail_1 & Rear_truss_2
Command: (1D + Type: Rod + Tolerance: 10 + Create)
Left_Rail_1 & Rear_truss_2
Command: (1D + Spot + Type: rod + Tolerance: 10 + Diameter: 1 + Create)
Refin plate & Front_truss_2
Command: (1D + Spot + Type: Bar 2 + Tolerance: 10 + Diameter: 1 + Create)
Front_truss_2 & Left_Rail_1
As creating a hinge connector. the demo,. are distorted and they, fixed through remesh and quality in index
Command: (Bolt, Type Hinge + Tolerance: 10+ create hole if none + create)
Final Model:
Conclusion:
This challenge was to get an idea of how to create ID or 2D or 3D connectors as well as spot weld as they have different types of connectors which is created in Ihe frame assembly.
