摘　　要：借助商业有限元软件MSC/Superform,数值模拟了火车车轮锻压热成形过程。利用节点跟踪功能研究金属质点流动规律。研究结果表明,轮坯金属质点对应于钢坯中原始位置,轮坯压制辐板内外侧面金属来自钢坯上下端角部,钢坯柱形外侧面金属呈环状流向轮坯轮辋周边,轮坯辐板和轮辋心部金属来自钢坯径向正中部位,钢坯径向内环区域金属形成轮坯轮毂心部,钢坯轴心区域金属形成轮坯冲块。数值模拟结果与物理模拟相吻合。The hot forming process of railway wheel was simulated by the commercial software MSC/Superforrn. Metal flow pattern was analyzed by the particle tracking method. Original places in billet of metal particles which formed the wheel were gained. Metal particles in back and front forging plate sides were from up and down billet corner place, Metal particles in billet columniation surface flowed into wheel web in circular direction. Metal particles in the center of wheel plate and web were from billet middle part along diameter direction. Metal particles in wheel hub center were from billet inner circle part along diameter direction. Billet axes center part formed wheel block. The result of numerical simulation is agreed with the physical simulation.
