摘 要 随着我国金属工艺制造行业的迅速发展，国内各大金属生产企业为了满足工业生产的需求不断开发出新型的金属产品。而金属板料拉深性能的测定方法研究一直是冲压成形领域的研究重点之一,新型轻质的金属板料在不断开发应用的过程中急需科学高效的冲压成形性能的评判方法。 为了在实验室600KN伺服压机的平台上设计一套在一定范围内通用的冲压实验系统，需要对圆筒形拉深试验方法进行充分的理论和CAE验证，得出可行的试验数据，用于圆筒形拉深试验方案设计和模具设计。设计一套通用圆筒形拉深实验模具，和通用冲压试验模架等一起组成冲压成形性能测定系统。 本文中通过使用DYNAFORM软件选择一套工艺方案进行CAE模拟验证，获得优化的工艺数据。设计一套通用圆筒形拉深实验模具。借助实验室已有的伺服压力机，对不同尺寸和拉深系数及板料厚度的金属板料进行实验。测定包括变形速度、变形程度、板料厚度等不同条件下拉深变形性能的变化规律。 关键词：圆筒形，拉深，CAE分析，DYNAFORM软件，通用模具 Cylindrical Deep Drawing and General Experimental Mold Design CAE Analysis ABSTRACT With Chinas metal craft manufacture the rapid development of the industry, domestic large enterprises to meet production metal industrial production requirement continuously develop new products.And sheet metal deep research of the performance measurement method has been forming research priorities,new lightweight sheet metal in the process of development and application in scientific and efficient stamping performance evaluation method. In order to design a set of within a certain range, the general stamping experiment system on the laboratory 600KN servo press platform,need for cylindrical deep experiment fully theory and CAE validation, get practical test data,used for testing scheme design of deep cylindrical and mould design.Design a set of general cylindrical deep drawing experiments mold,and the common punching test formwork etc together forming performance measurement system. In this paper through the use of DYNAFORM software process scheme for choosing a CAE simulation,to obtain the optimum process data.Design a set of general cylindrical deep drawing experiments mold.Using laboratory existing servo press, in different sizes and deep coefficient and sheet metal sheet thickness.Measurement includes deformation velocity and deformation degree, sheet thickness under different conditions, such as the deep deformation performance variation.
