By analyzing the forging process of double frustums sucker rod and using rigid visco-plastic material model and 3-D coupled FE simulation, the whole forging procedure are analyzed and simulated with finite element analysis software DEFORM. The results indicate the inner stress field, strain field, metal flowing law and forging travel-load curve during the forming procedure. The forming statuses, causation of defect of workpiece are predicted and so on.
