Challenge

Week 9-Creation of 1D Connectors Challenge

OBJECTIVES:

To mesh the given frame assembly and make connection at specified parts.

PROCEDURE:

1. MESHING:

Import the file frame_assembly_welding to hm under optistruct profile.
Click on AUTOMESH from 2D panel and mesh the given component accordingly.
Make sure that the elements pass all the element criteria properties. If failed, remesh the elements and use element cleanup.

2.CONNECTIONS:

SEAM WELD CONNECTION

quad elements:

spot weld:

Turn on front_truss_1, front_truss_2 and right_rail_1 and hide the remaiing components.
1d>connectors>spot and type as weld.
select the node list with number of layers 2 and components as well to connect.
set the diameter as 5mm, tolerance as 20mm, and click on create to connect the components.

hexa adhesive:

Turn on front_truss_1, front_truss_2 and left_trail_1and hide the remaining components.
1d>connectors>seam and type ad hexa(adhesive).
select the node list with spacing value as 5 and components as well to connect.
set tolerance as 10mm, and click on create to connect the components.

bolt connector:

turn on rear_truss_2, right_rail_2 and left_rail_2 and hide all the components.
1d>connectors>bolt and type as bolt(general)
select the node list and select create hole,if none to create hole for the bolt connection.
set the tolerance as 10mm, and click on create to connect the components.

spot weld with rigid elements:

spot weld with spring element:

REST ALL THE COMPONENTS ARE CONNECTED WITH SUITABLE CONNECTORS.

RESULT:

The frame assembly is meshed.
The connections are represented as specified.
Remaining components of frame assembly are connected by means of seam and spot welds.
