摘要汽车加强件是一个两端开口的复杂盒形件，对汽车加强件的拉深成形的研究和分 析，能够得到此类形件的通用拉深分析方法，以供实际生产使用。
本课题以汽车加强件拉深为研究对象，首先分析了汽车加强件的形状特点和拉深缺 陷的形式，建立了汽车加强件的三维模型并使用 Dynaform 软件对其进行拉深成形的有 限元分析，接着通过调整一系列的参数，包括温度、压边力、拉伸速率、圆角半径、拉 延筋布置方法和拉延筋深度以寻找各个参数的合适取值，最终通过正交试验获得最为合 适的参数组合。70132

Title Finite Element Analysis and Process Analysis of Deep Drawing of automobile strengthening panel
Abstract Automobile strengthening panel is a complex box shaped part with two ends opening. The study and analysis of the deep drawing forming of automobile strengthening panel can obtain the general drawing analysis method of the part. Automobile strengthening panel is chosen as the research object of deep drawing. Firstly, the form of parts of the shape features and defects in deep drawing are analysised. Then, the 3D model of automobile strengthening panel is established. Afterward, the finite element analysis of deep drawing are taken by Dynaform software. In order to find the most suitable drawing parameters, a series of parameters are adjusted, including temperature, blank holder force, stretching rate, radius, drawing bead arrangement method and drawing bead depth to find the appropriate value of the various parameters. Eventually, the most appropriate parameter combination is determined through orthogonal experiment.
Keywords Automobile strengthening panel; Finite element analysis; Dynaform; Orthogonal experiment
