摘要
文摘为了实现聚酰亚胺模塑粉的等静压近净成形,采用有限元软件ABAQUS对线性聚酰亚胺模塑粉的冷等静压(CIP)成型过程进行了模拟分析,利用Cam-Clay模型分析了圆柱体和长方体结构冷等静压成型前后的尺寸变化,并进行检验。结果显示圆柱体模拟与实验结果的误差在2.5%以内,长方体误差控制在4%以内,表明该模拟分析较准确预测了制件的尺寸变化。
In order to realize the near-net-shape forming of the polyimide molding powder, the cold isostatic press- ing（CIP） of linear polyimide molding powder was simulated by ABAQUS.The Cam-Clay model was used to analyze the change of the size of two types of blanks after cold isostatic pressing, and then the simulation results was verified by the experimental results.It is shown that the simulation deviation of the columnar blank can be controlled within 2.5%, and the error of cuboids blank within 4%.So this simulation method could predict the measurement accurately.
