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 energy theory, wrinkling criterion in deep drawing for axisymmetric parts is derived to take geometry parameters, friction coefficient, material properties, and the law of critical blank - holder force ( bhf ) of side wall wrinkling in the constraint condition of initial wrinkling into account
從能量平衡原理出發，通過對屈服準則的線性化處理，推導了考慮幾何參數、摩擦系數和材料性能參數、板材皺曲時約束條件的軸對稱拉深成形過程中側壁起皺臨界壓邊力的變化規律，給出了皺曲判據。 -
It is well known that additional stretching of the material in the unsupported wall area may prevent wrinkling, and this can be achieved in practice by increasing the blank - holder force ; but the application of excessive tensile stresses leads to failure by tearing
我們知道在不被支撐的拉伸壁區域中材料的外力拉伸可以防止起皺，這可以在實踐中通過增加壓邊力而實現，但是運用過大的拉伸力會引起破裂失效。 -
Adding injection on bottom or fore wall of cavity, based on chief injections on upstream, provides worse lean flameholding performance. experiments on the drag of cavity flame holder were conducted by force measurement system
