Tool set is the important parts of powder exact forming press. The dynamic character of tool set is the key to decide the working performance of press. The abnormal vibration of tool set will directly dam-age the forming quality and equipment in pressing course. This paper introduces FEM into the optimization design of exact forming press. The FEM soft MSC.Nastran is used by its modal analysis function on dynam-ics. Combining with the supporting soft MSC.Patran,the modal analysis is applied to the design of tool set. The dynamic character and design rationality are comparing analyzed,and the structural optimization is achieved based on the analysis result.
