Week 6 - Creating connection for Rear door

Aim : To perform connections for the car Rear door.

Procedure

1.After importing the model, first pid's are assigned to each respective part of car door, so that connections can be easily defined between the pid's.

2. Now Bolt connections are represented.

• first 3D point is created among any hole from PID's.
• Bolt connection is selected from connection type.
• From connection manager Bolt designation is selected all the PID's are assigned and search distance is assigned and connection is realized.

3. Now connection are made in the Hinge portion.

• Here first two RBE2 elements are created.
• Then a stem is created using the master node of both the RBE2 elemnts.
• As hinge has a motion along rotaional z-axis so we need to remove the 6th constraint while creating connection.

4. Now spot weld connections are made.

• When no hole is present to make connection between two PID's and are placed over each other so the type of connection we use in these situations is spot weld.
• RBE3-HEXA_RBE3 connection is used.
• First 3D point is created and then converted to spot weld point.
• PID"S are assigned in connection manager.
• Psolid properties are also assigned which determine the material.

5.Now rear door mirror ( wheather strips) connections are made. Connections are need to be make from inner and outer side.

• RBE3-CBUSH-RBE3 element is used.
• Seam line is generated first to make connection.
• PID is assigned because RBE element does not have its own PID. ALL the stiffness values are given.
• orientation of element is different so as per new industry guidelines orientation of all cbush elements is same as global orientation.

6. Door handle connection is made. Two RBE2 elements are generated and a another element is generated using master node of these elements and mass is assigned to it using CONMi.

Learning Outcomes:

• Learned where to use RBE2,RBE3, RBUSH-RBE3, HEXA-RBE3, seam line, spot line, 3D points while making connections.
• Learned how to change orientation in RBE3-CBUSH.
• Learned how to assign mass.
• Learned how generate Spot weld.

Conclusion: After doing this challenge i can make connections of complex parts as i gain good knowledge of different type of connections and there use in different conditions.
