By analyzing the relevant parameters of bending shaft through the theory of plastoelastic deformation, the model expressing the relationship between initial curvature and reverse curvature was inferred in this paper. The maximal initial curvature and its relevant location and maximal distortion can be gotten by numerical curve fitting after on-line measurement. According to calculation of the model between initial curvature and reverse curvature, the reverse curvature can be gotten, and the value of reverse curve can be calculated, and then it can offer accurate data for shaft straightening.
