WIRE BENDING OPERATION

AIM

TO Perform an analysis to simulate the bending of a wire using 3 different types of materials for the wire.

PROCEDURE

• Open ansys workbench .
• Update the material module as COPPER ALLOY (Nl).
• Geomtery - import-WIRE BENDING MATERIAL
• Model-edit
• Rename the model.
• Assign copper only to the WIRE (FRICTIONAL)
• Then create a contact between the wheels and WIRE (FRICTIONAL).
• Then create a contact between the WIRE and LEVER (FRICTIONAL).
• The normal stiffness factor = 0.1.
• Stiffness should be assigned to each iteration.
• Then Add offset ramped effects.
• Then create joints between The moDELS
• FIXED JOINT to WHEEL AND WIRE.
• REVOLUTE JOINT to LEVER.
• Then adjust the mesh type as tetrahedron .
• Element size on wire and lever 2.2mm
• THen define it has sphere of influence.
• Sphere radious of 7mm adn mesh size of 0.8mm
• Then upadte the analysis settings.

STRESS ( ALUMINIUM ALLOY)

MAX = 337.99 MPA

MIN =0.0026 MPA

STRESS ( ALUMINIUM ALLOY)

MAX = 337.99 MPA

MIN =0.0026 MPA

STRAIN ( ALUMINIUM ALLOY)

MAX = 0.00479

MIN =7.352E-9

STRESS ( MAGNESIUM ALLOY)

MAX = 254.5 MPA

MIN =0.0018 MPA

STRESS ( MAGNESIUM ALLOY)

MAX = 251.5 MPA

MIN =0.0018 MPA

STRAIN( MAGNESIUM ALLOY)

MAX = 0.0056

MIN =7.803E-8

STRESS(COPPER ALLOY)

MAX = 334.6 MPA

MIN =0.0041 MPA

STRESS(COPPER ALLOY)

MAX = 334.6 MPA

MIN =0.0041 MPA

STRAIN(COPPER ALLOY)

MAX = 0.0030

MIN =7.1201

CONCLUSION

• From above calculation

EQUIVALANT STRESS = COPPER ALLOY (MORE)

MAGNESIUM ALLOY (LESS)

EQUIVALANT STRAIN= COPPER ALLOY (LESS)

MAGNESIUM ALLOY (MORE)

• From the above analysis it is evident that MAGNESIUM ALLOY material posses less equivalant stress.
• It is evident that MAGNESIUM ALLOY POSSES HIGH EQUIVALANT SRAIN .

Since the copper experiences more stress ,it provides more resisitance to the bedning and hence it cannot be taken into account as favourable.

By far MAGNESIUM ALLOY undergoes much of deformation ,

Hence MAGNESIUM ALLOY is taken as the most prefarable material.
