Abstract
Cylindrical torsion bar spring is principal loading component in spring suspention of wheeled and track-mounted vehicles.Presetting torque is the key process to raise its loading capability.In this paper,torsional residual stress distribution produced by presetting torsion angle were calculated. Although it is useful to raise endurance of torsion bar for reduction of actual service stresses,the presetting torque must cause considerable damage to material.Thus the calculation of optimum presetting torque angle is necessary.
