Week 6 - Creating connection for Rear door

Week 6 Challenge report –

First of all, we need to separate PID wherever we want to make connection.

There are 3 types of connection we will be use in this particular challenge

1. C bush
2. Bolt
3. Hinge
4. Spot weld
5. Seam weld

1. C Bush connection – this we will be use between glass and their surrounding body.

• Create curve by using “Feat2curve” at the bottom of the glass.
• Translate(copy) at the transvers direction with distance 10.
• Translate(move) at the opposite transvers direction with distance 10.
• Repeat the same for second glass bottom too.
• Convert these curves to spot line.
• Go to connection manager.
• Select the converted spot line.
• Give Space as 10 and select P1(right click) as glass and P2 as surrounding body by shift+F1.
• Give connection type as RBE3CBUSH RBE3.
• Search distance – 20
• Select P bush by (shift +?).
• Provide new P bush and give the transfer and rotational by K1…K6 as 1,1,1,10,10,10.
• Then apply and realize.
• Repeat the same at all side of the glass.

2. Bolt connection – This we will be using where 2 holes are going to be constraint to each other.

• Create 3D point (by on COG) where we want to provide bolt connection.
• Convert 3D point to bolt.
• Select bolt by connection manager and select P1 & P2.
• FE representation type as “bolt”
• Provide search distance as 10-20.
• Then apply and realize.
• Repeat the same with bottom bracket.

3. Hinge connection:- This we will be using where we required 1 rotation motion rest all need to be fixed.

• Create 3D point (by on COG) where we want to provide bolt connection.
• Convert 3D point to bolt.
• Select bolt by connection manager and select P1 & P2.
• FE representation type as “bolt”
• Go to Nastran deck > elements> RBE2> 2 nodes.
• Give name as “hinge”
• Select centre of both bolts.
• CM to maintain as “12345”.
• Then apply and realize.

4. Spot weld- This we will be use between where 2 parallel endless surface occurring.

• Create 3D point (by on COG) at the centre of the shell where we want to create spot weld.
• Convert the 3D point to spot weld.
• Open connection manager and select the well and P1, P2 as both PID.
• Select FE representation type as RBE3-Hexa-RBE3.
• Provide search distance as 10.
• Then apply and realize.
• This weld will be solid weld.

5. Seam weld connection – This type of connection we are using where ended sheets are matching.

• create a curve by using the feature2 curve(Mesh>Perimeters>Feat2Curve) option.
• convert the curve to a seam line.
• open connection manager and we have to the PID’s(P1,P2)
• Fe representation - Overlap Shell (For Parallel Surfaces) or Y-joint Shell ( For Perpendicular Surfaces)
• Enter Search distance 10.
• choose the Proper base sheet.
• provide the width value as the target element size.
• create the weld pid.
• Then apply and realize it.
