摘要： 为了研究扭杆弹簧扭转精度对其强扭过程的影响，利用弹塑性理论对扭杆弹簧强扭过程进行了理论探讨，获得扭杆弹簧在屈服与塑性强扭工况下的断面应力、扭矩及残余应力等变化的数学模型.应用ABAQUS有限元软件对不同型号、强扭工况的扭杆弹簧进行数值模拟，分析了扭转精度对扭杆弹簧强扭效果的影响.结果表明，在强扭工艺允许范围内，扭转误差对扭杆弹簧强扭效果影响不超过5%.试验结果不仅验证了有限元模型的正确性，也得出扭杆弹簧强扭误差在不超过±1°工况下的强扭效果可近似等同的结论，此研究为扭杆弹簧强扭工艺的完善提供理论依据.

Abstract: In order to study the effect of torsion precision on pre-setting process， the elastic-plastic theory was used to discuss the pre-setting process of torsion bar spring. Then， a mathematical model changing with stress， torque and residual stress was obtained under yield pre-setting and plasticity pre-setting situation. The ABAQUS software was used to simulate torsion bar spring with different models and pre-setting situations， and the effect of pre-setting precision on torsion bar spring was analyzed. The results showed that the effect of torsion bar spring pre-setting process in the range of torsion error on pre-setting is less than 5%. The test data not only validates correctness of the finite element model， but shows that torsion bar spring with no more than ±1° pre-setting error can be seen approximately equivalent. The results provide a theoretical reference for improving the process of torsion bar spring pre-setting.

Key words: torsion bar spring, elastic-plastic, pre-setting process, numerical simulation, pre-setting test
