centrifugal symmetry 中文意思是什麼

centrifugal symmetry 解釋
離心對稱
  • centrifugal : adj. 1. 離心的 (opp. centripetal);應用離心力的。2. 【生物學】輸出的,排泄的。n. 離心機。adv. -ly
  • symmetry : n. 對稱;勻稱;調和;勻稱美。 bilateral symmetry 左右對稱。 radial symmetry 輻射對稱。
  1. As the deformation caused by centrifugal force is beyond the small deformation range, the large deformation effect was also taken into account in the equation. two models are constructed, one is of shrouded blade and the other is of bladed disc. the static natural frequencies and dynamic frequencies ( under 3000rpm ) are calculated by the finite element method and cyclic symmetry technique

    針對葉片的結構特點,採用適應較強的三維八節點實體單元模擬葉片,建立葉片運動微分方程;葉片?輪盤系統在高速旋轉時,受到離心力作用,使葉片發生大變形,故在方程中考慮了幾何大變形的問題;為研究葉根輪緣之間的接觸狀態,建立了考慮葉根?輪緣接觸的有限元方程,利用拉格朗日增廣演算法來求解該方程,確定葉根輪緣之間的接觸面狀態。
  2. The results indicated that the centrifugal force reduces the localization ; when the young ’ s modulus of all blades are in the tolerance of 5 %, the blade - disc can regarded as an cyclic symmetry system

    結果表明,離心力對失調葉片輪盤系統局部化振動有減弱作用;所有葉片彈性模量在5 %誤差范圍的隨機失調系統,其固有頻率與非失調相差很小,即失調葉片?輪盤系統可以按照循環對稱結構進行模態分析。
