Create connectors and attach them to 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.
About CONNECTORS:- It is a geometric entity that defines the connection between other entities. It is used for welding, bolt, adhesive.
→ It links geometry or FE entities.
→ Types of connectors:-
1. Spot:-
* Connection at a point.
* Spot welds, rivets, etc.
2. Bolt:-
* Connection at hole location.
3. Trim mass:-
* Non-physical mass.
* Simplification through replacement of parts with mass only or adding mass to existing parts.
4. Seam:-
* Connection along a length.
* Connects geometry only.
5. Area:-
* Connection of Areas.
* Adhesives.
Procedure:-
→ Import the given truss and rail assembly.
→ Perform 2D mesh operation based on the given quality criteria.
Create connectors:-
1. Right rail2 & front truss1:- Seam(angled+capped+L)
This connector can be created from the seam types connectors.
(2D↵connectors↵seam↵type: seam(angled+capped+L)↵tolerance 10↵select components and nodes then create.)
2. Left rail 2 & front truss 1:- Quad elements
It is also connected through seam type of connectors.
3. Front truss 2, front truss 1 & right rail 1:- spot weld with 2 layers and 5mm diameter.
It is a spot-type weld with 2 layers and a 5mm diameter.
4. Front truss 2, front truss 1, and left rail 1:- Hexa(Adhesive)
This could be created with the help of seam type of connectors.
5. Rear truss 2 & right rail 2:- Bolt connector
Use bolt type option. Since there is no existing hole so we have to choose to create a hole option.
6. Rear truss 2 & left rail 2:- Bolt connector
Do the same operation, that we did above.
7. Right rail 1 & right rail 2:-Spot-weld with rigid elements.
For rigid elements select the spot-weld option.
8. Left rail 1 & left rail 2:- Spot-weld with spring elements
This is also done through spot type connector.
9. For the remaining types, I used the following connectors;-
a. Rear truss 2 & right rail 1:- Bolt type
b. reinforcement plate and front truss 2:- Hexa (Adhesive)
c. Reinforcement plate and front truss 1:- Spot-weld
d. Left rail 2 and front truss 1:- Quad type
RESULT:-
CONCLUSION:-
Have gained about connectors and their uses.
