Based on the construction features of the Upper Beam of Large Open-die Forging Hydraulic Press,a finite element model has been established by using large-scale finite element analysis software I-DEAS,and the structural stress and displacement of the upper beam under all sorts of loads have been analyzed.

根据某大型自由锻造油压机上横梁的结构特点，利用大型通用有限元分析软件I-DEAS建立有限元模型，并对上横梁进行了静力学的有限元分析计算，研究了在满负荷工作状态下上横梁的结构应力以及位移情况。

Aiming at solving the difficulties of prototype manufacturing of conical ring for the steam generator shell of 600MW Nuclear Reactor,this paper developed a new techniques for the prototype manu-facturing of the great conical ring utilizing ring rolling technology based on RAW200/160-5 ring rolling.

1引言600MW蒸汽发生器壳体是核电站的关键设备，由封头、锥形环件和筒体组焊而成。以往制造这种锥形环件所采用的办法是，先锻制环形筒件再采用机械加工方法成形或者采用自由锻造方法直接在水压机上锻制出大型锥形环件，但这些工艺既费工时又大量浪费材料，而且产品精度不高[1]。

Rom forging to rolling, from sheet metal to titanium Simufact.forming has been developed to support in all forming applications, independent from process temperature, machine used or material processed: closed die forging or extrusion, drawing, upsetting, bending or free forging, flat rolling, profile rolling or tumbling cold, hot or semi-hot, mechanical press, hammer or screw press, rolling machine or orbital forging even coupled processes and spring-controlled tools, simple low-alloyed or stainless steel , aluminium or non-ferrous metal, titanium or nickel based alloys, massive or sheets, material flow or dieload analysis Simufact.forming is the integrated simulation environment for the optimization of all forming processes.
