Finite Element Analysis of Double Cup Extrusion Process with Fluttering Container

  • 摘要: 阐述挤压筒颤振辅助双杯挤压成形机理,运用Deform-3D有限元分析软件进行数值模拟仿真,分析比较不同施振参数下的行程载荷、材料流动速度、杯高比及等效应力分布。仿真结果表明挤压筒颤振可降低平均行程载荷,其平均行程载荷的最大下降值随颤振速度的提高而增加,但对实际挤压力影响不明显;上杯材料流动速度随颤振速度的提高而减小,下杯材料则相反;当颤振速度小于下杯材料流动速度时,杯高比大于无颤振时的值,且随颤振速度的提高而增加,而当颤振速度大于下杯材料流动速度时,上杯材料流动速度方向会出现反向,杯高比小于无颤振时的值,并随颤振速度的提高而减小;邻近挤压筒侧的塑性变形区随颤振周期性上下运动,但并不改变最大等效应力。
