Solution
First Import the file by going to file-import-model(or other according to file type)-select file-import
Then check for any geometrical errors
If there is any use quick edit option to solve those errors
Now move on to meshing
Before meshing ,set criteria settings by going to preference-criteria file settings
Now start meshing by going to 2D-Automesh-select surf-mesh
There are Nine Components here and do the meshing one by one
1.Front truss1
2.Front truss 2
3.Reinf plate
4.Right Rail 1
5.Right Rail 2
6.Left Rail 1
7.Left Rail 2
8.Rear Truss 1
9.Rear Truss 2
#Now Assign Thickness
To Assign thickness , create Material by right click and create Material and select the material you want
Now create Property by right click and create property-then select property and new dialog box will appear
then give thickness and then after that assign it to all components.
property card Assign the property by right clicking on component and assign the property
After giving thickness and viewing in 2D detailed element representation
#Creation of 1D Connectors
1.Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected seam)-then click
on type to use from the following connections.
Give spacing 5,give tolerance 10 and give weld angle and other things as per the requiremnents.
Now select nodes and components
Now, click on create
It is done but not Realised,so right click and click on Realise and then blue mark will turn to green
Now,It is Realised
2. Left_Rail_2 & Front_truss_1:- Quad elements
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected seam)-then click
on type to use from the following connections.
Now select nodes and components
Done.
3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 2 Layers and 5 mm Diameter
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected Spot)-then click
on type to use from the following connections.
First I have spot weld the Front_Truss_2 and Front_Truss_1 and Then Front_Truss_1 and Right_Rail_1.
select nodes and components
Done and Realised.
4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive)
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected seam)-then click
on type to use from the following connections.
select node and component
done
now for second part
Realised.
5. Rear_truss_2 & Right_Rail_2:- Bolt Connector
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected bolt)-then click
on type to use from the following connections.
select node and components
Done and realised.
6. Rear_truss_2 & Left_Rail_2:- Bolt Connector
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected bolt)-then click
on type to use from the following connections.
Select node and component
Done and realised.
7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected Spot)-then click
on type to use from the following connections.
Select nodes and component on both sides one side at a time
second side
Done and Realised for both sides.
8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected Spot)-then click
on type to use from the following connections.
Select nodes and component on both sides one side at a time
Second Side
Done and realised for both sides.
9.Connections for other Parts
#Reinf plate,Front truss1,Front truss 2:(HEXA ADHESIVE)
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected Seam)-then click
on type to use from the following connections.
now select nodes and components
Done and Realised.
#Rear Truss_2,Right_Rail_1,Left_Rail_1:(HEXA ADHESIVE)
To use connectors first go to 1D-Connectors -select the connector you want (here i have selected Seam)-then click
on type to use from the following connections.
ALL CONNECTIONS ARE DONE
CONCLUSION
Connected the components using connectors.
Creation of 1D Connectors is Done.
