Create a connector and Attach the various parts of the given model

1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)

2. Left_Rail_2 & Front_truss_1:- Quad elements

3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 2 Layers and 5 mm Diameter

5. Rear_truss_2 & Right_Rail_2:- Bolt Connector

6. Rear_truss_2 & Left_Rail_2:- Bolt Connector

7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements

8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements OBJECTIVE : Objectives:

1. To check the geometrical errors in the CAD model.
2. To check the CAD Topology and CAD Clean Up.
3. To extract the Mid surface for all components of the CAD model and assign thickness to the mid surface.
4. To achive mention qualitiy criteria and features of the model have to be captured properly with good mesh flow.
5. To mesh the each mid surface for better mesh flow.
   1. To create suitable connection for the given model.. TYPES OF CONNECTIONS: 1. BOLTS CONNECTION 2. SEAM WELD CONNECTION 3. SPOT WELD CONNECTION 4. C-BUSH CONNECTION 1.BOLT CONNECTION: Bolt connection is used to connect two or more than two mating parts temperary so in hypermesh we have RBE2 to connects the bolts with the help of two or many node RBE2. In RBE 2 we require slave nodes and master nodes for making the connection.

2.SEAM WELD CONNECTION : Seam welding is a permanent joining process between two mating parts. In hypermesh we have to know what is the lenght of connection so we create a curve and apply seam weld line on them and seam quard angle+ capped +L we use connection type as seam line and deplopy the connection in connection manager,seam weld line is created now, we select overlap seam weld in connection manager and seam weld RBE3 SEAM is created. .SPOT WELD CONNECTION: Spot weld is permanent joint between two mating part where we required more load carring capacity at a joint and represented by RBE3 HEXA.We set a COG point and apply spot weld after that we go connection maneger select part p1 and p2 and realise. Spot weld with RIGID ELEMENT

5.Result: we create diffrent types of connection where is required wirh the help hypermesh. 6. LEARNING OUTCOMES : We learn how to create connection for given model,like weld, seam,bolt connection with connecor 8.Conclusion: we create a different types of connection for given model
