At the same time we study, analysis and discuss the action that non - linearity - stickiness - springiness and crazing damage of the pmma sample under creep though making us of the knowledge about the high molecule physics the damage theory of material of rheology of bodies with defects. through the study and theory analysis of single - axes stretching experiment in pmma sample under creep, take the surface crazing damage density of pmma sample as an variable, to look for a commonly rule that the crazing damage of pmma, and to offer a feasible damage model for the sake of study that of pmma ' s remoteness damage
同時運用高分子物理、含缺陷流變性物體的材料破壞理論等知識,對無孔洞pmma試件和有孔洞pmma試件蠕變條件下非線性粘彈性行為及其銀紋損傷現象進行了研究、分析與探討,通過對蠕變條件下的pmma試件的單軸拉伸實驗研究和理論分析,以pmma試件的銀紋損傷面密度值為損傷變量,來嘗試尋求pmma銀紋損傷的一般規律,為研究pmma的細觀損傷提供了一種可行的損傷模型。All of the hydraulic structures are arranged in the right bank and four underground seepage tunnels are arranged parallel in horizon, and the axle wires intersect with syncline axis almost perpendicularity, and with rock formation obtusely. complex underground tunnels are formed under such formidable conditions, and each of seepage tunnels crosses nuclear of syncline and comes up against interlaminar sharing disturbed belt at different footage
四條引水發電隧洞在平面上平行布置,軸線方向與本區構造線方向近於垂直,與巖層走向大角度相交,構成一復雜地下洞室群,並在不同洞段通過沙金壩向斜核部,且遭遇多條層間剪切錯動帶。The reason analysis of the formation of surface pores on quenched camshafts
凸輪軸重熔淬火表面孔洞缺陷形成原因分析The numerical simulation was made on this kind of energy dissipator by using the k - s turbulence model, the full - field distribution of the time - averaged parameter and the turbulence parameter are described in detail, the calculated time - averaged pressure has good agreement with the experimental results, some advice can be provided for the further study and application in this thesis, especially the calculated results can be used to check the lowest time - averaged pressure
本文對洞塞式消能工採用軸對稱的k -模型進行了數值模擬,數值模擬結果詳細地描述了時均流參數和紊動參數的全場分佈,計算所得的壁面時均壓力結果與實驗結果相吻合,獲得了實體試驗難以獲得的流動特徵。可供這種消能工的進一步研究和應用提供參考,特別是可用於檢驗壓力最低點的大小。In the model, johnson - cook strength is combined with gurson - tvergaard - needleman yield criteria, and random distribution of microvoids is used. results show that quasi - periodic axial fracture will appear, which obstructs the mirror current of the armature
在給定微孔洞的初始擾動時,計算結果解釋了鋁電樞表面將要形成的不穩定性,它導致了電樞外表面出現周期性的軸向裂紋,阻礙了鏡像電流,使fcg損耗增加。In underground engineering, the cavity axis should be designed to intersect fractures with large - angle ( 90 ) as it traverses fault and joints
摘要在地下工程中,當洞室穿越斷層、節理等破碎帶時,應盡可能使洞軸線走向與破裂面的走向呈大角度相交( 90 ) 。( 2 ) using tractor as power, makes it mobile and agile, and, the tractor can be used to do another work if it is not used to drive the tunnel. the tractor with simple hoist implement can assemble the wind tunnel by use of the oil cylinder of tractor itself without another special implement
( 2 )使用拖拉機為動力,機動靈活,實驗時,使用一根傳動軸連接拖拉機和風洞實現動力傳遞,實驗后脫開連接不影響拖拉機其它方面的使用,同時,拖拉機配備簡易的吊裝架后利用液壓懸掛可以吊裝風洞,從而不必為風洞配備專用吊裝設備。There is short of specific and simple calculating method to obtain the cavity axis ' orientation, especially for the rocks with many fractures
然而如何設計洞室軸線走向與破裂面走向大角度相交,一直缺乏具體而簡易的計算方法,尤其在破裂面較多且產狀明顯不同時,這個問題更為突出。分享友人
