根据大变形小残差的矫直理论得到矫直机压下量,通过建立9辊矫直过程有限元仿真模型,对Q460 20号角钢矫直过程进行模拟,考虑了材料的加工硬化得到了其矫直过程的应力应变分布,以及各矫直辊矫直过程中矫直力、矫直力矩的动态变化过程,为开发设计新型矫直机提供了理论依据。
According to the straightening theory of large deformation and small residuals, the amount of straightening machine is obtained. Through the establishment of the finite element simulation model of 9-roll straightening process, the straightening process of Q460 20 angle steel is simulated, and the work hardening of the material is considered Straightening process of stress and strain distribution, as well as the straightening process straightening force straightening force, straightening torque dynamic process of change, to develop a new type of straightening machine provides a theoretical basis.
