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。 -
Testing of ion exchange resins - determination of bead size distribution
離子交換樹脂的試驗.樹脂珠粒粒度分佈的測定 -
The position of the trajectory depends on the ratio of bead - to - fluid density, the ratio of bead - to - disc radius and the reynolds number which describes the operating conditions of the stirred media mill. by means of the beads motion in the calculation domain, the influence of different comminution operation parameters on comminution results is discussed. those parameters mainly include the beads size, beads density, stirrer angular speed and liquid density and viscosity etc. those parameters are optimized so that the comminution results are improved
通過研究研磨介質在計算域內的運動來探索不同的粉磨技術參數對粉碎效果的影響，這些粉磨技術參數主要包括磨介尺寸、磨介密度、攪拌盤速度、液流密度及粘度等；通過優化這些參數來達到提高攪拌盤式攪拌磨粉磨效果的目的。 -
From internal details to entire bead shape, the glass beads are processed at each step completely by hands with great varieties different in style, size and form
