摘要: 用MARC/Autoforge有限元軟件，對圓坯一次橫鍛過程進行了三維熱—力耦合數值模擬．研究了金屬變形的發展、流動規律，其結果與物理模擬研究的結果相吻合．還分析了工件的應力分布以及工具與工件的接觸應力分布形態．通過分析發現：在圓坯一次性橫鍛過程中，盡管工件端部靜水壓力不大．但存在較大的橫向拉應力．

Abstract: With the aid of FE code MARC/Autoforge, two-roll cross-forging process was simulated, and the development of deformation and the law of metal-flow were studied. The result from the simulation is in good agreement with that of the physical simulations. The stress distribution in the work-piece and contact pressure between the work-piece and tool were also analyzed. It is discovered that in cross-forging process with only one strike of the press large lateral stretch stress exists, although the hydrostatic pressure is positively small in the center of the round.
