利用Dynaform有限元分析软件对大尺寸煤浆槽上下叶片进行了成形模拟。通过对成形极限图的分析,预测了成形缺陷,重点对成形后回弹量进行了研究。结果表明:通过FLD图能分析判断出成形的可行性,确定了叶片的回弹值。在模拟中修正补偿能大大减少叶片的回弹量,这能为后续的模具制造提供理论依据。 Dynaform finite element analysis software was used to simulate the forming of the upper and lower blades of large size coal slurry tank. Through the analysis of the forming limit map, the forming defects were predicted, and the amount of springback after forming was emphasized. The results show that: Through the FLD chart can be analyzed to determine the feasibility of forming, to determine the blade rebound value. Correcting the compensation in the simulation can greatly reduce the springback of the blade, which can provide a theoretical basis for subsequent mold manufacturing.
