contact-time test 中文意思是什麼
contact-time test
解釋
接觸率試驗-
A series of tests were performed on the self - made fretting wear test rig to examine the fretting wear of steels, by taking the wear depth of steel wires as a characterization parameter describing the fretting wear in relation to contact load and fretting time. the results demonstrates that the fretting wear depth increases with the increasing of the contact load and fretting time
結果表明，鋼絲試樣的微動磨損深度隨著接觸載荷和微動時間的增加而呈增長趨勢，但由於接觸面積和接觸應力在微動磨損過程中隨著接觸載荷和微動時間的變化而變化，使磨損深度在不同磨損工況下增長趨勢不同。 -

It directly affects the engine ' s working reliability whether it ' s good or not. according to the past method, piston can only be decided whether it meets the need of engineering in test after it has been turn out. this paper simulates the real working condition of piston by combining the ked method and fe - contact analysis way. it reflects deforming rule of piston, and makes it possible that the structure problem of piston skirt can only be found during the design period, so the cost of developing new product is lowered and the time is shorted. this paper proves that the thought is practical and the result of simulation to piston lr4100 is in accord with practice
活塞裙部形線是活塞的關鍵結構之一，它的好壞直接影響發動機工作可靠性，以往的判定方法只有在活塞加工完成後，才能通過實驗方法判定設計，能否滿足工程實際的需要，本文通過ked方法與有限元接觸方法的結合，模擬實際活塞工作情況，較為準確的反映出，活塞裙部的變形規律，在設計階段發現活塞裙部的設計結構問題，節省新產品開發成本，縮短開發周期。 -
A lot of indoor and in - suti test to the properties of the chemical grouting material, especially the properties requested by actual engineering has proceeded. active - diluent of furfural - acetone, low poison hardener. surfactant and a series of formula have been selected by experiment. cw series material has low glue degree, time last of it harden can be adjust, surface tension and contact angle of the material is low
對漿材性能特別是工程實際對漿材要求的性能進行了大量室內、現場試驗測試，選擇性能優良的糠醛?丙酮活性稀釋劑、低毒憎水性固化劑、表面活性劑及系列漿材配比， cw系漿液粘度、固化時間大范圍可調、表面張力及接觸角小、漿材固化及固結強度高，具有優良的浸潤性能和工藝性能。 -
Based on the formula which is used to compute the lateral resistance of single pile deduced by wang qitong, a formula is setup whose precondition is that the pile and the lateral soil directly around the pile deform in - phase. on the basis of that the contact stress of the foundation is equal, a formula that can be used to conform the stress - ratio of the composite ground is set up, on the same time, the principles of the deformation harmony of the soil and the piles in the composite ground are also discussed. combining with results of this test, a formula which can calculate the bearing capacity that considering the effect of group piles of the composite ground is also deduced
視攪拌樁樁體為均質彈性介質，推導了復合地基中單樁有效樁長的理論計算公式；根據王啟銅柔性樁樁側摩阻力計算公式，以樁側土與樁體協調位移為前提推導了柔性樁樁側摩阻力的計算公式；以基底接觸應力均勻分佈，樁體、樁間土均質為前提，討論了樁，土協同工作原理，從而得出復合地基樁、土荷載變形特性，以及樁、土應力比計算公式；結合本次試驗，通過計算加載時樁體與土體的荷載分擔情況以及在極限狀態下樁土承載力發揮值，提出考慮群樁效應的攪拌樁復合地基承載力計算公式。 -
