simple interest

The wing is modeled structurally by vibrational modes , which are used as amplitude of motion by a finite element analysis . conservative full - potential equation and three dimensional unsteady euler equation are used to compute the unsteady transonic flows around airfoil and wings under simple harmonic motion 以給定機翼模態分布下機翼上各點的模態值作為運動幅值,以三維非定常全位勢方程和三維非定常euler方程為控制方程,求解三維機翼簡諧運動下的非定常氣動力。

Assuming the blades conduct a planar simple harmonic motion , the flows in vibrating cascades in the case of different oscillating amplitudes , different reduced frequencies and different torsional centers are computed respectively for two blade profiles . according to comparing flow calculations at different oscillation modes , the influence of the oscillation parameters “ selection on aeroelastic performances of cascades is analyzed 假定葉片做平面簡諧運動,針對兩種葉型分別計算了不同振動幅度、折合頻率及扭心位置時的振動葉柵流場,根據各種振型下流場計算結果的比較,分析了振動參數選取對葉柵氣動彈性性能的影響。

Cosine acceleration or simple harmonic motion 余弦加速度運動

One instance of simple harmonic motion is that of the projection on any diametre of a point which describes a circular path with uniform angular velocity . 當一質點以勻角速度作圓周運動時,則它在任意直徑上的投影的運動便是簡諧運動的一例。
