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。Since the dichromated gelatin has a higher diffraction efficiency in all holographic recording materials, the aim of this research is to use dichromated gelatin as the recording material and to make use of the principle of holography to design holographic optical components, especially in fabrication procedure of dichromated gelatin film and in experimental technique to form a high diffraction efficiency using different angular exposure method
為了產生優質的聚焦能力與效率，本研究採用目前具有最高繞射效率（ 80 ~ 90 % ）的重鉻酸明膠材料作為感光劑，除了自行調制藥劑比例成分，並依嚴格的製作步製成重鉻酸明膠全像片外，並採用不同角度重覆曝光方式改良干涉式波帶板無法自動追蹤的缺點，經過多次試驗與改進，藉以形成具備高繞射效率和自動追蹤功能的全像光學波帶板。Through the simulation of the forming process, we can get the deformations, stress, strain, plastic flowing in sheets and the interface state under impact load and rolling load, the deformation of the sawtooth form and comparing to the initial state, the results above are expressed in computer animated way. and the effect of geometrical ( mainly different form, including 90 degree, isoceles triangle ， 75 degree, and 1. 5 high and wide ), material and technical parameters on the bond strength are analyzed, also including the comparison of different sawtooth form. the optimum parameters are got
對雙金屬復合板成型過程進行模擬，從而得到在沖擊載荷和軋輥壓力作用下基板和覆板的應力、應變分佈和塑性流動變形規律，復合后的齒形的變形情況與初始齒形形成對比，以動畫的方式模擬成型過程，並分析了不同幾何參數（主要是不同的齒型，其中包括直角齒型、等腰齒型、 75度齒型、 1 . 5高寬齒型） 、材料參數、工藝參數對復合強度的影響，以及不同齒型的變形對比以及齒型對復合情況的影響，提出最優齒型、最優工藝參數，有效地指導了實驗。The article relates that the tool ' s measurement precision has been improved by applying cycling acquisition method, self calibration function and phase - sensitive detector. the image coverage rate is improved and reached to 60 percent by increasing the number of pad ' s buttons. the tool carried out two logging functions : fast - scanner mode and dip mode
