vortex shedding frequency

基本解释

It also shows that the frequency at first peak has more direct relations to the vortex shedding frequency of the upper cable.
拖缆的涡激振动响应的第一峰值频率与拖缆上端的旋涡发放频率有比较直接的联系；
Besides, in case the vortex shedding frequency is equal to a inhere frequency of rod, the rod will arises the vortex shedding resonance or called vortex resonance.
并且当漩涡脱落频率与杆件的固有频率接近时，杆件会产生漩涡脱落共振或称涡激共振。
Meanwhile the vortex shift waveform is obtained from the estimated mean frequency waveform using a suitable low-pass filter. Then the vortex shedding frequency and amplitude can be calculated.
用合适的滤波器可以从估计出的平均频率曲线中得到涡流的波形，并且计算表征涡流的涡流经过频率和幅度特征参数。
