Week 4- Rolling operation

OBJECTIVE: TO SIMULATE THE ROLLING OPERATION ON A WORKPIECE MADE OF COPPER AND GENERATE VARIOUS RESULTS ASSOCIATED.

CASE SETUP: STATIC STRUCTURAL IS SELECTED FOR THE ANALYSIS AND IN THE ENGINEERING DATA COPPER ALLOY NL IS ADDED.

NOW THE GIVEN CAD MODEL OF THE ROLLING OPERATION IS IMPORTED IN MODEL AND IS EDITED IN SPACECLAIM ACCORDING TO THE GIVEN SPECIFICATIONS.

COPPER ALLOY NL MATERIAL IS SELECTED AS THE MATERIAL FOR THE WORKPIECE WHEREAS STRUCTURAL STEEL IS ASSUMED FOR THE THE ROLLERS.

CONTACTS ARE GIVEN SUITABLY FOR THE ROLLERS AND THE WORKPIECE SPECIFYING CONTACTS AND TARGET REGIONS.

CYLINDRICAL JOINTS ARE GIVEN FOR THE ROLLERS WITH THE SPECIFICATIONS AS SHOWN.

MESHING IS DONE BY SELECTING BODY SIZING OPTION FOR THE WORKPIECE INORDER TO GENERATE FINE MESH FOR THE WORKPIECE TO ACQUIRE RELIABLE RESULTS WHILE SOLVING.

ANALYSIS SETUP IS DONE BY SELECTING STEPS OF EXECUTION TO BE 14. DISPLACEMENT IS SELECTED FOR THE SIDE SURFACES OF THE WORKPIECE AND THE DIRECTION IS SELECTED AS NEGATIVE Y AXIS. AND SUITABLE INPUT IS GIVEN FOR 90 MM DISPLACEMENT.

ROTATION JOINT LOAD IS SELECTED FOR THE ROLLERS AND SUITABLE TABULAR DATA IS GIVEN SO THE THE ROLLER 1 RORATES IN CLOCKWISE DIRECTION AND ROLLER 2 ROTATES IN ANTICLOCKWISE DIRECTIONS WITH REFERENCE TO THE AXIS OF ROTATION ASSUMED BY US EARLIER.

VARIOUS REQUIRED RESULTS SELECTED TO BE EVALUATED AND THE SOLVE OPTION IS SELECTED.

RESULTS AND CONCLUSIONS: THE MAXIMUM EQUIVALENT STRESS IN THE WHOLE SIMULATION IS FOUND TO BE 3870.9 MPa.

THE MAXIMUM PLASTIC STRAIN IN THE WORKPIECE IS FOUND TO BE 2.3427.

DIRECTIONAL DEFORMATION FOR THE WORKPIECE IN Z DIRECTION IS FOUND TO HAVE A MAXIMUM VALUE OF 6.0812 mm.

THE DIRECTIONAL DEFORMATION FOR THE TWO END FACES OF THE WORKPIECE HAVE AN EXACT DISPLACEMENT OF 90MM IN Y DIRECTION WHICH PROVES THAT IT HAS TRAVERSED 90MM SUCCESSFULLY.

THUS THE SIMULATION OF THE ROLLING PROCESS IS SUCESSFULLY DONE AND RESULTS HAVE BEEN GENERATED.
