Chagan sag is a secondary tectonic unit in chagandelesu depression, northeastern yingen - eji ' naqi basin, and the basement of the basin is a paleozoic fold belt of continental margin or island arc at the connection region of north china plate * tarim plate and kazakstan plate, with the character of erogenic belt. in working area and its adjacent area, the forming tectonic setting of indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction ; that of early yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse ; and that of early cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase
查干凹陷屬于銀根?額濟納旗盆地東北端查干德勒蘇坳陷內的一個次級構造單元，其盆地基底為古生代時期華北板塊、哈薩克斯坦板塊和塔里木板塊交接部位形成的陸緣或島弧褶皺帶，具有古生代造山帶的性質。研究區及鄰區印支期侵入巖形成於造山帶強烈擠壓陸內俯沖的構造環境；燕山早期侵入巖形成於由擠壓轉向拉伸、造山帶的增厚陸殼開始發生伸展垮塌的構造環境；早白堊世火山巖形成於造山期后進一步發生伸展垮塌的區域構造環境。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。The meso - cenozoic evolution of bachu fault - uplift is closely related to its south and north subsiding foredeep. under the background of indian plate subducting under asia - europe plate, bachu forebulge was greatly affected by the development of southwest depression and awati depression. almost all of its structure reversed, and as a result of it, both of its south and north boundary migrated. according to its evolution history and its feature, the authors tentatively use both - side migration model to interpret the evolution of compound forebulge. since triassic, almost all the spheres above lithosphere synchronously became flexure. because transpressional stress field became increasingly strong, bachu forebulge continued uplifting and big faults formed. then, bachu uplift, as a whole, slipped upward along those big faults and showed migrating toward thrust zone in plane. in tectonic tranquility, the lithosphere bounded back and in consequence of it, bachu uplift slipped down and showed migration toward craton, at that moment negative inversion structures developed. while the forebulge migrated toward its south and north foredeep, it was very possible that locally extensional stress appeared in the forebulge
在印度板塊向歐亞板塊俯沖的大背景下，巴楚前緣斷隆受西南坳陷和阿瓦提凹陷的影響，新生代時構造體制發生反轉，邊界向南北遷移。根據其發育過程特徵，作者用復合前緣隆起兩端遷移模式對復合前緣隆起獨特的構造發育史進行了解釋：即三疊紀以來巖石圈各圈層同步撓曲變形。隨著擠壓應力場的增大，巴楚隆起在撓曲基礎上不斷抬升，形成幾條大型斷裂帶。Concave printing board comes in two types of square board and circular board, which can customize various kinds of needed typing symbols
