摘　　要：LG-730冷轧管机是国内最大规格伺服控制型两辊轧机,本文建立了其机架装配应力应变有限元模型,分析了LG-730机架装配在最大载荷下的变形和应力分布,在此基础上,对轧机结构进行了优化:两边机架底座宽度各减小了10 mm,机架筋板厚度由原来的120 mm减小到100 mm,机架两边厚度各减小了20 mm。优化后机架重量降低了,机架的刚度和强度分布更加均匀合理。研究结果对LG-730机架结构设计具有指导意义。LG-730 cold pilger rolling mill is the largest two-roll servo-controlled rolling mill,and the housing assembly FEM analysis model of which is developed in this paper,and then the deformation and stress distribu-tion of the saddle is analyzed under the maximum rolling force.On the base of the previous work,the saddle structure optimization is done：the width of the saddle base is reduced 10 mm,the thickness of the rib of the saddle is reduced from 120 mm to 100 mm,and the thickness of the whole saddle of reduced 20 mm.The results show that the weight of the saddle is reduced,and the stiffness also the strength of the saddle are less affected,so the calculated results have the important advising meaning for the LG-730＆#39;s structure design.
