基于理想弹－塑性模型，对半精加工自紧－时效圆筒的应力状态进行了分析，导出了残余应力的数学表达式，计算了模拟钢管的残余应力值，采用Ｓａｃｈｓ镗削法测定了模拟管的残余应力值，并将二者作了比较。结果表明，理论预期值与实验测定值吻合较好，从而证实了理论分析的可靠性。
Based on the ideal elastic-plastic model, the stress state of semi-finishing self-tight-aging cylinder was analyzed, and the mathematical expression of residual stress was deduced. The residual stress of simulated steel pipe was calculated. The Sachs boring method was used to determine the simulation The residual stress of the tube is compared and the two are compared. The results show that the expected value of the theory is in good agreement with the experimental value, which confirms the reliability of the theoretical analysis.
