Creating connection for Rear door

ANSA JULY BATCH -1

AIM:-

Create 1D connections for the given model .

THEORY:-

A car door is a type of door opening, typically hinged on its front edge, but sometimes attached by other mechanisms such as tracks, for entering and exiting a vehicle. Doors most often integrate side windows for visibility from inside the car and can be locked to secure the vehicle

PROCEEDURE :-

1. open the model :-

2. we first group the model parts into different pids

3. create connections for handle . give rbe2 connections for handle and give mass in tonnes to it .

• go to nastran deck and click rbe2(many nodes) and click one of the handle and middle click and asssign property for the rigid and give the dof for the handle.
• for handle all the dof has to constraint . same like for another joint make a rbe2 connection and assign the property and dof.
• use conmass to give mass to the handle .

4. give cbush connections for all sides of mirror .we have to give cbush because the glass the adjacent panel will have some elastic material ,so we should not connect that with the rigid.

• first select edge of a mirror and convert it into curve using feature2curve function in mesh deck.
• now convert the curve to spot line .
• go to connection manager , select the curves and give required parameters . and click apply and realize .

5. bolt connection for hinges and support .

• we first create 3D point using 'on COG' in points to create a center point where bolt to be placed .
• after that we convert that point to bolt.
• then we use connection manager and select that point and give required parameters .

6. spot weld for horizontal member and hinge support

• we first create 3D point using 'on COG' in points to create a center point where spot weld needed .
• after that we convert that 3d point to spotweld point .
• then we use connection manager and select that point and give required parameters .

7. we use rbe2 connection for other holes in the model

LEARNING OUTCOME:-

• learned how to make different connections like bolt , spot weld , seam weld , cbush , rbe2 .
• learned how to assign mass to element .

CONCLUSION :-

we have successfully made 1D connctions on the side door and proper mass is given where its required .
