Aim :
To create 1d element on the rear door.
Solution :
First we will discuss about the various 1d element present :
1D Elements are simple connections between nodes.
Standard 1D Elements are:
1.RBE2 :
Rigid link to transfer motion from the Independent node to the dependant nodes.
2.RBE3
3.Beam / Bar :
Others include :
Now we will create connections for the following part :
Now you can see the all the surfaces are defined in a single part as shown below :
We will separate this and make different part ids as shown below :
We have assigned different part ids as shown below :
Now we will create connections as shown below :
We will define the connectors at the hinge of the side door highlighted in red as below :
We will create 3d points at the bolting holes using cog command and later convert them into bolt points :
Now we will create a bolt connector as shown below between the 4 surfaces which are to be connected , we have select 4 parts in place of P1 ,P2 ,P3 and P4 as shown below :
As you can see we have defined P1 to P4 and given it bolt connector property and later realized it . We get the connector as shown below :
In the similar manner we have created bolt connections at the following places :
Now for the hinges we will create rbe2 element which will constrained in all dofs and between these two rbe2s create an element which has freedom to rotate in z direction so that it can rotation of the hinge.We have created rbe2 at the following places :
We have constrained it in all dofs and created an rbe2 element which is in constrained in 5 except in dof of z rotation:
In this way we have created the hinge joint , now we have applied the rigids elements at the following places :
Now at the doot lock we have created the rbe 2 elements and added a mass at the central rbe2 element as shown below :
Now we create connections for the window region as shown below :
We have created curves for taking reference .
We have converted them into spot lines as shown below :
Now we have created the above connector between the glass and the door as we need to make it rigid and have stiffness in all 6 directions , therefore we have created this :
In the same manner we have connected all 4 sides of the glass as shown :
Conclusion
Therefore we have added connectors wherever needed.
