Creating Connectors in Hypermesh
Aim:
To use the connectors to attach different parts of the assembly togeather, the parts are attached through appropriate connector.
CAD model of the given component.
Procedure:
1. Import the given CAD model into the hypermesh.
2. If the components are sold extract the midsurface and delet the solids by retaining the surface.
3.Mesh the geometry using automesh option form 2D panel.
4. Check for the 2D mesh quality and repair the failed elements.
5. Creat the material card and property card for the components and assign the materail and propery to all the components of the assembly.
creating the connectors.
1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)
Seam quad( angled+Capped+L) connector between two components.
procedure.
1. go to connectors from 2D pannel, select seam from the list.
2. Select the nodes where you want the connector to be generated.
3. select two components between which you want the connectors.
4. From type select Seam quad( angled+Capped+L) form the options.
5. set the weld angle, Cap angle and runoff angle for the connector.
6. form the mesh option select Quad transition and imprint option, and click creat.
7. If the mesh is altered, fix the mesh using 2D automesh option.
Spacing is distance between two weld elements.
Tolerance is the distance around which is searches the nodes to connect. (distance between the two components )
Weld angle is between 0-60°
Cap angle is between 45°-90°
runoff angle is between 0-45°
2. Left_Rail_2 & Front_truss_1:- Quad elementsQuad connector between Left_Rail_2 & Front_truss_1
procedure:
1. go to connectors from 2D pannel, select seam from the list.
2. Select the nodes where you want the connector to be generated.
3. select two components between which you want the connectors.
4. Select Quads from the type, and click creat.
5.If the mesh is altered, fix the mesh using 2D automesh option.
The settings are shown in the below image.
For property we can creat a new property for the weld and apply it to the weld by selecting the specific propert by clicking propert tab.
5. If the created connector is in yellow, it unrealized, go to realize and select the yellow nodes and realize the connector.
4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive)
Hexa Adhesive between Front_truss_2, Front_truss_1 & Left_Rail_1.
Procedure:
1. go to connectors from 2D pannel, select seam from the list.
2. Select the nodes where you want the connector to be generated.
3. select two components between which you want the connectors.
4. From the type select hexa (adhesive) and specfy the number of strips, number of coats and width of the adhesive.
5. If the mesh is altered, fix the mesh using 2D automesh option.
Hexa position to edge : it is used to place the adhesive strip with respect to the edge.
5.Rear_truss_2 & Right_Rail_2:- Bolt Connector and Rear_truss_2 & Left_Rail_2:- Bolt Connector
Rear_truss_2 & Right_Rail_2 connected with Bolt connector.
Rear_truss_2 & Left_Rail_2 connected with bolt connector
Procedure:
1. go to connectors from 2D pannel, select Bolt from the list.
2. Select the nodes where you want the connector to be generated.
3. select two components between which you want the connectors.
4. Check the other options, tolerance and generate hole if none.
5. Set all the options as per requirment and click creat.
6. If the mesh is altered, fix the mesh using 2D automesh option.
Bolt connection option.
6.Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements and Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements
Right_Rail_1 & Right_Rail_2 :Spot weld with RBE2 elements.
Right_Rail_1 & Right_Rail_2 : RBE2 elements between two components.
1.go to connectors from 2D pannel, select Spot from the list.
2. Select the nodes where you want the connector to be generated.
3. select two components between which you want the connectors.
4. To creat rigid elements select rigid from type and for spring i.e Elastic elements select spring from type.
5. Check the other options, toleranc and Diameter.
6. If the created connector is in yellow then it is not realized, to realize the connector go to realize and select the connectors and ralize.
7. If the mesh is altered, fix the mesh using 2D automesh option.
7. Rear_Truss_2 and Rear_Truss_1:- Spot-Weld with Sealing elements
Spot-Weld with Sealing Elements.
conclusion:
The different components of the assembly are now connected togeather with appropreate connectors uing Hypermesh.
