摘　　要：以某H型钢矫直机为研究对象,建立H型钢矫直三维模型。利用ANSYS/LS-DYNA有限元动力分析软件,对型钢矫直过程进行动态仿真。仿真分析结果验证了所建立的矫直仿真模型比较合理,表明了此种分析方法具有较高的可靠性。得出上、下辊矫直力的变化图,重点分析了H型钢截面在矫直过程中三个阶段的应力变化规律,这对H型钢矫直机工艺参数的设定具有一定的指导意义。Taking an H-beam straightener as the research object,a three-dimensional straightening model of H-beam is established.The finite element dynamic analysis software ANSYS/LS-DYNA was used to simulate the straightening process of section steel.The simulation results verify the rationality of the straightening simulation model,and show that the analysis method has high reliability.The change chart of straightening force of upper and lower rolls is obtained,and the stress variation law of H-beam section in three stages of straightening process is analyzed emphatically,which has certain guiding significance for the setting of technological parameters for H-beam straightener.
