Abstract：

For the current problem that the straightening amount of long pipe parts in China relied heavily on manual experience and had low straightening accuracy and low efficiency, the calculation model of the straightening amount of long pipe parts was studied. Then, based on the elasto-plastic deformation theory, the relationship between the straightening force and the deformation deflection of long pipe parts was clarified by exploring the deformation law of long pipe parts in the process of straightening, and the calculation model of straightening amount was derived and established, which could calculat the required straightening amount of pipe parts under certain initial deformation. Furthermore, the programming calculation for the model was realized by Matlab, and the simulation of the straightening process of the long pipe parts was carried out based on software ANSYS, which verified the calculation accuracy of the model. The verification results show that the relative error between the model calculation results and the simulation analysis results is less than 10%, and the accuracy is high, which can be used as an important reference for formulating the straightening amount.
