symmetry tolerance 中文意思是什麼
symmetry tolerance
解釋
對稱公差-
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。 -
Cyclic symmetry in blade - disc assembles is often destroyed by small differences in the individual blades ’ structural properties that result from manufacturing and material tolerance, this phenomenon commonly knows as mistuning
葉片?輪盤的周期對稱性經常由於製造、材料以及非均勻磨損和其他因素被破壞，引起系統出現失調現象。
