摘要
Abstract
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.关键词
