中文摘要:采用平行辊矫直原理,建立了辊距不等的九辊强力矫直机的矫直力数学模型,并针对某厂9辊强力矫直机矫直60mm厚Q345中厚板采用弹塑性有限元法ANSYS/LS-DYNA建立中厚板矫直过程的三维动态有限元分析模型。揭示了矫直力在各辊上的变化规律,以及该厂矫直60mm厚Q345中厚板矫直工艺的合理与否。
英文摘要:Based on principle of parallel roller straightening, establish mathematical model of straightening force for nine-roller powerful straightening machine with unequal roller spacing and three-dimensional dynamic finite element analysis model of straightening Q345 60mm thick plate by nine-roller powerful straightening machine of a factory using the elastic-plastic finite element method ANSYS / LS-DYNA. Reveal the straightening force variation rule on the straightening rollers and straightening process of straightening Q345 60mm thick plate for a factory reasonable or not.
