stress wrinkle 中文意思是什麼
stress wrinkle
解釋
應力皺紋-
Abstract : in this paper, through stress analysis of region about conical and spherical parts during drawing, a calculating formula of maximum tangential compressive stess in unsupported wall region is deduced. and this is condition of causing internal wrinkle. then on the premise to guarantee not breaking workpiece, a critical calculating formula is presented
文摘:通過對球形和錐形零件在拉深過程中各部分的應力分析，得到了拉深過程中懸空區切向壓應力最大值的計算公式，以此作為引發內皺的條件，在保證工件不被拉裂的前提下，建立了臨界計算公式。 -

通過圓筒形及盒形件拉深前後網格變化分析，並確定變形區和非變形區，由此得到不規則盒形件毛坯展開形狀由不變形區和參與變形拉深線組成，並用此方法計算出汽車制動閥安裝板的毛坯形狀和尺寸，在試模時一次即獲得成功，具有一定的實用價值。 -
The model analysis of the deployed beams were studied in both theory way and simulation way. the differences of the beams in different pressures were studied. investigations showed that the method of modeling for short and long rolled beams is doable ; the process of fold maybe lead so large displacement and stress that membrane is damaged at local areas, ration and material wrinkle generates,
研究結果表明:本文提出的分別針對短、長捲曲折疊充氣管的建模方法是有效的;在充氣管展開過程中，充氣速度越大，展開的速度越快，但由於阻尼損耗，二者並非線性關系;充氣速度過大不利於結構展開過程的穩定性;充氣支撐管的氣壓越大其固有頻率越高，但影響效果很小。
