  1. In the paper, the finite element simulation software dynafrom is applied to analyze the affect of different blank holder during the forming process of laminose stepped tubular part, predict the possible defects such as wrinkle and break, obtain the rational style of blank holder avoiding the occur of defects and determine the rational configuration of die. the forming affect of thin - wall shallow stepped tubular part is analyzed when using different lubricate condition ( friction coefficient ). by this method, the relationship between friction coefficient and drawing depth of laminose stepped tubular part is obtained

    本文利用有限元模擬軟體dynafrom分析了不同類的壓邊圈對薄壁階梯筒形件形過程的影響規律,測了採用不同類壓邊圈時可能出現的形缺陷如起皺和拉裂,獲得了防止缺陷產生的合理壓邊圈形式,確定了合理的模具結構形式;分析了不同的潤滑條件(摩擦系數)對薄板階梯筒形件形的影響,獲得摩擦系數與薄板階梯筒形件的拉深深度的關系;分析了階梯筒形件形過程中的不同階段的應力應變分佈、材料厚度變化情況,並獲得了階梯階梯筒形件能一次拉深形的條件。
