Week 9-Challenge
Objective :
Import given model to hypermesh software.
Check the model thoroughly for any solids or surfaces and for mid surfaces.
Mesh the given model using automesh and go for quality.
Add the connectors for the model as given below,
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 3 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 :
- Import the given model to the hypemesh software and select the optistruct solver.
- Now check the given model throughly and go for meshing, because here given model is in midsurface so no need to again for midsurfacing.
- Here I am meshing the model individually because quality of mesh is important and I am taking 5mm for the mesh.
- After completing the mesh now go to connectors option in that go to seam and select the seam quad (angled + capped +L) and select the components which you have to connect and make sure that connectors are realised. This is for Rght rail 2 & Front truss 1. For this connectors spacing is given 4mm and Tolerance is 20mm.
- Same for Left rail 2 & and Front truss 1 instead of above connector select the quad connector and select the omponents to connect.
- To do spot weld in frame go to spot opton in connectors and select the weld in 3layers and 5mm diameter.
- For Hexa adhesive connectors to the seam and select the hexa and selct the components to connect and create the connector.
- For bolt connectors go to bolt option and select the two nodes and create the bolt connector between the two components. this for rear truss 2 & right rail 2 and rear truss 2 & left rail .
- For the right rail 1 and right rail 2 go to the spot option and selct the rigid elements.
- For the left rail 1 & left rail 2 go to same aoption from above point but select the spring element.spring
- For remaining I have selected the rod and bush elements to connect remaning parts.
Results :
Thus the connectors are created for given frame and make them realise using the hypermesh software.
Conclusion :
Thus I have learned how to connect the parts with the help of connectors and uses of connectors in hypermesh software.
