中文拼音 [chùtóuyālì]
觸頭壓力
英文
contact pressure-
It will effect the system in safety and running economy directly > test of tradition past the method is an usage to give or get an electric shock the bridge method or direct current to press to decline the method to proceed to measure, and the electric current for producing of is only in the ma class which ca n ' t broke through the oxidize surface
高壓斷路器是電力系統中最重要的控制和保護設備之一，它對系統的安全、經濟運行有著直接的影響。以前傳統的測試方法是使用電橋法或直流壓降法進行測量，所產生的電流僅在ma級，不能擊穿觸頭氧化膜。The summation of forces on extensor mechanism should be zero according to equilibrium rules of forces before and after total knee arthroplasty based on constant extensor moment
計算得到髕骨形位參數變化前後與伸膝機構相關的動力學參數，包括股四頭肌力、髕韌帶力及髕股關節接觸壓力的變化。It is difficult to estimate indent depth in theory. this paper presents two methods to estimate the relationship between dent depth and contact force, respectively amend method and deflection compensate method, which are developed by using a clear geometrical relation to express indent, incursion profile and deflection difference
本文以一種新的觀點，用一個明確的幾何關系來確定壓痕、壓頭與板的接觸面剖面及接觸中心點與邊界點之間的撓度差三者之間的關系，提出兩種近似預測接觸力與壓痕深度關系的方法? ?修正法和撓度補償法。The crimped head design, prevents solids from dislodging the seal face, allows the seal to withstand higher pressure and rotational speed and eliminates the metal shell from contacting the seal ring
波紋式頭部設計，防止固體顆粒從密封面上撞出，使得密封能夠抵抗更高的壓力和旋轉速度，避免金屬殼接觸到密封環。Thereby, this paper has carried through an in - depth study on wear mechanism between tool joint of drill pipe and casing, problems caused by wear and measures to deal with wear based on researches at home and abroad. the research contents include : in order to reveal mechanism of wear occurred between tool joint and casing, distribution of the contact pressure between the tool joint and casing for different loads was obtained with finite element method. furthermore, the mathematical model of maximum contact pressure and the wear depth on casing was established
所以，本文在國內外研究的基礎上，對鉆桿與套管摩擦磨損的機理、引發的系列問題及其預防措施進行了深入研究，研究內容主要包括：為探討鉆桿接頭與套管摩擦磨損的機理，採用有限元法研究了不同載荷下接頭與套管之間接觸壓力的分佈規律，並建立了最大接觸壓力與磨損量的數學模型。分享友人
