pressing factor
解釋
壓縮系數-
But there is a main question that pvdf does not be in p phase with higher piezoelectric property, but be in other phases with lower or without piezoelectric property, thus, which can not improve distinctly piezoelectric constant d33, reduce notably dielectric spoilage ( tg5 ) and raise remarkably mechanical coupling factor ( kp ) of 0 - 3 pzt / pvdf piezoelectric composite, so these will restrict its development and application. in this paper, 0 - 3 pzt / pvdf piezoelectric composite will be prepared by room pressing - solidity, high - temperature - pressing and room - pressing techniques respectively
由於這個壓電復合材料體系存在一個主要問題? pvdf在0 ? 3型pzt / pvdf壓電復合材料中通常不是以具有較強壓電性的相晶態形式呈現，多是以其它的相態存在，不能有效地提高0 ? 3型pzt / pvdf壓電復合材料的壓電常數d _ （ 33 ） 、降低介電損耗tg和增大機電耦合系數kp等壓電和介電性能，從而嚴重地制約它的發展和應用。 -
Systole is pressed and pressing of arteries and veins is rate of cardiovascular ill die in one ' s bed and complication occurence rate is the most important forecast an element, in this age group, pressing of arteries and veins increases is the mainest factor that assesses risk, but it is accompanied almost always have systole period high blood pressure
收縮壓和脈壓是心血管病病死率和並發癥發生率的最重要的猜測因素，在此年齡組，脈壓增大是評估危險的最重要因素，但它幾乎總伴有收縮期高血壓。 -
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。 -
