Week 6

OBJECTIVE

This week, the connection of the front door is shown in detail and the different types of connection techniques along with different 1D elements.

Now for the given rear door FE model, apply the same technique and the elements to implement the connections.

STEP:1

IMPORT THE MODEL IN NASTRAN DOMAIN OF ANSA

FIG1: FE MODEL OF REAR DOOR

STEP 2: DRAW A CURVE ALONG THE EDGES OF GLASS OF REAR DOOR USING FEATURE 2 CURVE COMMAND

STEP3: CONVERT THE CURVE TO CONECTION USING CONVERT CONNECTION ENTITIES

STEP4: OPEN CONNECTION MANAGER AND SELECT THE CURVES ONE BY ONE AND ASSIGN THE RBE3-CBUSH-RBE3 FOR ALL THE WEATHER STRIP ARAOUND THE GLASS SHIELD

STEP 5: REALIZE THE CONNECTION

FIG 2: CBUSH CONECTION

STEP 6: FOR THE DOOR HANDLE ASIGN THE OPENING RBE2 CLUSTER AND THEN A SINGLE CONNM AT THE MASTER NODE

FIG 3: CONNM ASSIGNED TO DOOR HANDLE

STEP 7: FOR DOOR HINGE JOINT RBE2 JOINT AT ALL HOLES USING MANY NODE WITH 123456 DEGREE OF FREEDOM TO BE ASSIGNED AT CM AND THE CENTRE NODE TO BE GIVEN 12345 DEGREE OF FREEDOM.

FIG 4: RBE2 JOINT FOR HINGES.

STEP 8: SPOT WELD AT ALL THE JOINTS WHERE PIPE BRACING FOR INNER DOOR

FINAL RESULT

LEARNING: LEARNED IN DETAIL HOW TO ASSIGN THE RBE2,RBE3 CBUSH, SPOT WELD RBE2 CLUSTER CONNECTION TO FE

CONCLUSION : DIFFERENT JOINTS NEEDS TO BE ASSSIGNED FOR ALL TYPES OF CONNECTION FOR FINAL SIMULATION
