Week 9 - Creating connection for Rear door

AIM:

Creating the connections for the rear door of a car.

PROCEDURE:

• Open the Ansa work bench ANSA v22.1.0.
• Import the given model from the downloads
• In ANSA we can import all the CAD Software file formats like IGES,STEP,etc.
• The model consists of the many Region.

GIVEN MODEL:

CREATE SUITABLE CONNECTIONS:

• First we have define the each region into PID.
• And then we have go for connecting it.

CREATING RBE2 CONNECTIONS:

• RBE2 can be used to define the rigid body and is used in bolts connection .
• NASTRAN DECK>>ELEMENTS>>RBE2>>MANY NODES>>SELECT NODES>>OK

the below image is the connection between 2 master nodes using rbe2>>two nodes

CREATING RBE3 CONNECTION:

• RBE3 connection is done for cbush and spot weld .

CBUSH CONNECTION:

• first make curve by using Feat2curve from Classic mesh
• make curve on both sides of glass by 10 mm gap on each side by using copy option from Transform.
• and then assign the curve as spot line.

• after assigning the spot line in connection manager select the spot line ,select the RBE3>>CBUSH>>RBE3 and create a cbush pid and given necessary data.
• after that cbush is created.

SPOT WELD CONNECTION:

• for spot weld first we have to create the cog point after that assign the point as spot weld point.
• after assigning the spot weld go to the connection manager and select spot weld point.
• after selecting it,select RBE3>>hexa>>RBE3 and provide the necessary data .
• the spot weld is created.

LEARNING OUTCOMES:

• Learned new tools related to connections.
• Learned to assign weld,bolt and cbush points and curves.

CONCLUSION :

Therefore the connections are made for the given rear door of the car.
