Week 9-Creation of 1D Connectors Challenge

AIM

To mesh the given geometry and deploy connections mentioned below

OBJECTIVE

1.Mesh the component by using 2D shell elements by using given criteria

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

I meshed the components of the frame assembly by using 2D shell elements and cleared quality criteria by using

cleanup tools and edit element tools in 2D pannel

CONNECTIONS

SEAM WELD

seam weld is created by seam options in connectots in 1D & 2D panels

There are different types of seam welds , the type of weld used is seam quad(angled+capped+l)

If the connectors are in green color mean connections are relaized if the colour is red means connection not relized

ADHESIVE-HEXA

ADHESIVE-HEXA connection for Front truss 2, Front truss 1

SPOT WELD (WELD ELEMENT)

spot weld for Front truss 2, Front truss 1 & Right Rail 1

SPOT WELD (RIGID ELEMENT)

Holes are filled with rbe3 elements so as to eliminate unwanted deviation of fem and equal distribution of load
