Week 9-Creation of 1D Connectors Challenge
Objectives: To attach the parts of given model using specific connections after clean up and meshing said parts.
Requirements:
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:
* The model is cleaned up and meshed with proper mesh flow.The mesh type is fixed and element size is taken as 5mm. It is a 2d mesh since the entire model comprises of extracted midsurfaces.
a. Right_rail 2 and Front truss 1: seam-quad(angled+capped+L)
For this,we can isolate the right_rail_2 and front_truss_1 srfaces and find the region of possible connection to add connectors.
The connectors option can be accessed fro 2d menu.This is seam connector so the option is selected. 2D>Connectors>seam.
The location option lets us select which nodes will involve the connectors and the 'connect what' lets us select the components that need connecting.furthermore, we need to specify the time of seam connector through 'type' where we can select 'seam quad (angled+capped+L). if specified we can alter the option like weld angle, cap angle and runoff angle.furthermore, tolerance needs to be varied accordingly so the connector option can find the next part to connect and ensure realization.
b. Left_rail_2 & front_truss_1: Quad elements.
The same process is followed in isolating and picking the nodes to be connected. the quad connectors is under the same seam option. it just needs to be selected from the type menu.its the same procedure again with picking the nodes and selecting the components and assigning the tolerance .
c. Front_truss_2 , Front_truss_1 &Right_rail_1: spot weld with 2 layers and 5mm diameter.
Again, the particular components are isolated .this connector will involve 2 layyers (components).
The elements are selected along with 2 layers and the tolerance is assignes along with the diameter. the process is straightforward.
d. Front_truss_2,Front_truss_1&Left_rail_1:Hexa (adhesive).
To access the adhesive connector, it is under the seam connector options.2D>connectors>seam and the types needs to be hexa(adhesive).input the criteria and select the nodes and components.
e. Rear_truss_2, & Right_Rail_2 & Rear_truss_2 & Left_rail_2: Bolt Connector.
Similar process again. the components to be connected are isolated and we pick the nodes through which the connectors will be placed .since this is a bolt connectors, two should be adequate. the bolt option can be accessed from the connectors menu( 2D>connectors>Bolt). we can assign the tolrance ,select the nodes and components. also, the 'create hole', if none' option is selected .
f. Right_Rail_1 & Right_Rail_2 :- Spot weld with Rigid Elements & Left_Rail_1 & Left_Rail_2:- Spot Weld with Spring Elements.
The elements are isolated and all the nodes along a single line of the entire components are selected for spot welding.the only difference being the type in these cases. the first case will have 'rigid' for type and second will have 'spring'.
Conclusion: The given model was meshed and after meshing, the componeents included were connected using specified connectors and were realized.accordingly, appropriate connectors were used on other components of the same model.
