失速颤振 meaning in Chinese

stall flutter
stalling flutter
whirl flutter

Examples

  1. The characteristic of " lock - in " can be used to explain all kinds of nonlinear phenomenon of the stall flutter
    这种频率锁定规律可以清楚地解释失速颤振的各种非线性现象。
  2. Firstly , the airfoil ' s classic flutter ( at small attack angle ) , stall flutter ( near the static stall angle ) and response ( at large attack angle ) are analyzed . it is found from the numerical results that " lock - in " will occur at certain freestream velocity range near the static stall angle , where the frequency of the vortex will be equal to the natural frequency and the flutter has the characteristic of self - induced oscillation . when the attack angle is far from the static stall angle , the vortex will have its own frequency , which differs from the natural frequency , and the flutter has the characteristic of forced oscillation
    首先研究了二维翼型的古典颤振(小攻角) 、失速颤振(失速攻角)和动力响应问题(大攻角) ,得到以下结论:在静态失速攻角附近的一定来流速度范围内,分离涡会发生频率锁定现象,分离流的频率与固有频率趋于相同,这时的振动呈现自激振动的特点;远离失速攻角时分离流频率则摆脱固有频率的影响,此时的振动具有强迫振动的特点。
