摘　　要：本文以压力机组合机身的预紧理论为基础,通过分析预紧过程确定了热模锻压力机的预紧系数,提出预紧修正系数的概念,并对二者做了区别分析,最后借助有限元分析软件对2500t热模锻压力机预紧过程进行分析,证明了该预紧系数选取的合理性,为以后处理类似问题提供了借鉴。Based on the preload theory of the combined frame body of the press,the preload coefficient of the hot die forging press is determined by analyzing the preload process,and the concept of the preload correction coefficient is proposed,and the difference between the two is analyzed.Finally,the preload process of the 2500t hot die forging press is analyzed by using the finite element analysis software,and the rationality of the selection of the preload coefficient is proved.It provides reference for dealing with similar problems in the future.
