This paper referred to the massive domestic and foreign technical material, elaborated in the sheet forming value simulation theory essential technology in detail, points out when analysis sheet forming question should use the big distortion ball plasticity fem and introduce the application characteristic and the function summarizes of the sheet forming simulation software dynaform. secondly, analyzed the cover forming characteristic, simultaneously introduced the influence cover forming factor in detail : such as ramming direction, the craft addendum surface and the material pressing surface, the radius of convex - concave mold, draw bead, pressure strength, blank size and craft margin and so on. and simulates many typical automobiles cover panel with software : such lateral board, back taillight pedestal and storage cover
其次，分析了覆蓋件成形的特點和要求，同時詳細介紹了影響覆蓋件成形的因素如沖壓方向、工藝補充面和壓料面、凸凹模圓角、拉延筋、壓邊力、坯料尺寸和工藝切口等，並用數值模擬軟體對多個典型的汽車覆蓋件汽車后側圍板、后燈座以及轎車后備箱蓋的沖壓成形情況進行模擬，用模擬結果優化拉延工藝方案，比較了內覆蓋件和外覆蓋件在成形特點和要求的一些異同點，以及常見的起皺、拉裂和回彈、成形不足等缺陷的產生機理和相應對策，重點介紹工藝補充面和壓料面的設計及優化方法，因為拉延是沖壓工藝的關鍵工序，而工藝補充面和壓料面的設計是拉延工序的關鍵，對消除缺陷至關重要。 -

Based on the experimental results and the correlative chemistry theory, the phases formed in the process and its influenceable factors were studied. the significant results were enumerated as follows : as for the mn - h2o system, 5g pure mn scraps ( 99. 5 %, - 200mesh ) and distilled water served as the starting materials were milled by high energy ball miller together with 200g steel balls as the milling medium. the experiments were conducted with the rotation speed of 380rpm. - mn3o4 nanopowders were fabricated after milling some time and would experienced phase transformations if continue to be milled. the reaction would be accelerated if a little of hcl or mnso4 was added while be decelerated if. a little of naoh was added. the - mn3o4 phase with particl size between 20 ~ 100 nanometer was obtained after milling 1. 5h when trace hcl was added. the oxygen added to the ball tin has little effect on the reaction
主要實驗結果如下: （ 1 ）對于mn - h2o系，通過高能行星式球磨機，在50ml蒸餾水中球磨5gmn粉末，球料比為40 : 1 ，轉速為380rpm ，球磨一定時間后獲得了納米級單相- mn3o4 。隨著球磨時間的延長，生成的- mn3o4會繼續被氧化或發生晶型轉變。加入微量hcl或mnso4會明顯加快mn的反應，加入hcl后，球磨1 . 5h后即獲得粒徑為20 100nm的單相- mn3o4粉末;加入微量的naoh會抑制mn反應生成- mn3o4 。
