How to pronounce "subharmonic vibration""subharmonic vibration" in a sentence
TranslationMobile
  • 次谐波振动
  • 分频振动(频率是基频的分数)
  • 分谐波振动
Examples
  • A new phenomenon is found numerically and experimentally : even if the rotating speed of the rotor is lower , the subharmonic vibration of the rotor - bearing system may be occurred under great disturbance ( unbalance )
    通过理论计算和分析发现:提出了即使在较低转速的情况下,只要外激励(不平衡量)足够大,也有可能导致转子出现油膜涡动或者失稳的现象。
  • In this thesis , a multi - disk rotor supported by two plain journal bearings is used for the numerical and experimental studies . the one aim is to analyze the nonlinear dynamic characteristics of the rotor system under different varying parameters ; the methods of online elimination of the oil whip and subharmonic vibration are developed and studied also . besides the expression of the nonlinear oil film force is proposed , so that the unbalance of the nonlinear rotor system may be identified online
    作者在总结了前人大量的有关非线性振动研究工作的基础上,确立了本文的研究目标:一是以工程应用为背景,研究转子-轴承系统由非线性油膜力引起的非线性振动特性以及各种影响因素,力图通过对转子-轴承系统非线性振动特性的分析,找到切实可行的在线消除油膜振荡的办法;二是研究非线性油膜力的表达方法式,使非线性转子系统的不平衡量在线识别成为可能。
