利用ABAQUS/Explicit分析了6 mm钢板经17辊矫直机矫直过程压弯量对板形和残余应力的影响。结果表明,入口压弯量7.2 mm,出口压弯量-2.6 mm时得到的矫直钢板板形良好,残余应力分布均匀。17辊矫直机的第2、4辊的压弯量应当适当增大,使塑性变形比接近极值,保证矫直质量。 ABAQUS / Explicit was used to analyze the effect of bending amount on the plate shape and residual stress during the straightening process of 6 mm steel plate through 17-roller straightening machine. The results show that the straightening plate shape obtained when the inlet bending amount is 7.2 mm and the outlet bending amount is -2.6 mm is good and the residual stress distribution is uniform. The 17th roller leveler flexural capacity of the 2nd and 4th rollers should be properly increased so that the plastic deformation ratio close to the extreme, to ensure the quality of straightening.
