Abstract Torsionbar is a component automobilethat has beendesigned makethe vehicle of to lighter and smaller Sincethis component automobileis underthe periodic cycles in resistance the fatigue is very important For this reason it is necessary various to that operationsbe applied on the Torsion bar to enhancethe fatigue resistance The prestressing an importantoperationin the productionof Torsionbar Suitablerang is of strain applied in presettingoperationhas beensuggested torsion bars which for their heat treatment is through hardening This rang is 2xL 2xL 0 022x BRad 0 044x However no rang has beensuggested torsIon for d d bars which has beenundersurfacehardening This studyis to obtain suitablerang of strainfor this type of Torsionbars In this investigationthe serviceload applied on the torsion bar is calculated The E module which is necessary this calculatation obtainedfrom tensiletest in is Thenthe torque angle curvewas drawnby the useof a presetting machine Excel and Minitab softwares were then used to calculatethe spring module shear module and yield torque of this type of torsion bar Thenthe depthof plastic zone wascalculatedby the useof the following formula I 4 p3 Ty 3 Furthermore safetymodule is usedto calculatethe optimumtorque to be used in a presetting torsionbar by new p of i j ifi L I I AIIIW4 A
