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分析了不同類型的壓邊圈對薄壁階梯筒形件成形過程的影響規律，預測了採用不同類型壓邊圈時可能出現的成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）對薄板階梯筒形件成形的影響，獲得摩擦系數與薄板階梯筒形件的拉深深度的關系；分析了階梯筒形件成形過程中的不同階段的應力應變分佈、毛坯材料厚度變化情況，並獲得了階梯階梯筒形件能一次拉深成形的條件。 -
Based on calculation method on unfold size and piece form, theory analysis and research are given on ellipse, circle tube, box as equal - high, irregular, unequal - high, irregular piece, process and condition on possibility of drawing are introduced, through calculation coefficient, number of drawing, drawing testing dies are made, results are given, it is similar to calculation method, in the same time, complex drawing presswork is planed, to avoid wrinkle, critical in drawing process. in this paper, die designing is introduced based on complex drawing unfold size calculation, press center is automatic calculated, apartments of press tools are calculated too with material mechanic production process and press form are better, period of die designing is to reduced, and cost of product is lower
對基於復雜拉深件展開尺寸計算的模具設計也作了詳細的論述，指出了現有復雜拉深件模具設計製造程序的不合理性，本文在復雜拉深件展開尺寸基礎上自動生成沖裁中心、沖裁周長，運用材料力學中桿件強度及抗失穩條件，實現對沖壓模具參數的自動計算，簡化了沖壓模具彈性元件、打料裝置的設計過程，給出了沖壓模具結構設計流程，使得模具材料核算，製造過程，沖壓方式更趨合理，縮短了模具設計製造周期，降低了產品生產成本。 -

The model analysis of the deployed beams were studied in both theory way and simulation way. the differences of the beams in different pressures were studied. investigations showed that the method of modeling for short and long rolled beams is doable ; the process of fold maybe lead so large displacement and stress that membrane is damaged at local areas, ration and material wrinkle generates,
研究結果表明:本文提出的分別針對短、長捲曲折疊充氣管的建模方法是有效的;在充氣管展開過程中，充氣速度越大，展開的速度越快，但由於阻尼損耗，二者並非線性關系;充氣速度過大不利於結構展開過程的穩定性;充氣支撐管的氣壓越大其固有頻率越高，但影響效果很小。
