Abstract：

Starting from the inclined roller straightening principle and the elastic-plastic deformation mechanism, the main parameters of ten-roller straightener, reasonable data of straightening roller type and optimized data were given, a three-dimensional finite element model of straightening roller was established. By using MARC，the straightening process of ten-roller straightener for pipe simulation was simulated, the influences of bending amount，flattening amount，straightening speed and roller angle on straightening effect were researched and the optimal straightening parameters were determined. The influence laws of parameters on straightening quality were analyzed and the straightening effect was optimized，then the optimal straightening scheme was put forward.Finally，the reliability of the scheme was verified.
