本发明能增强动、静盘涡旋线体舌的受力强度，可有效的延长使用寿命。
Vortex-induced vibration is limited amplitude response, but it occurs at low wind speed with relative large amplitude, which will affect the strength and fatigue resistance of the structure.
尽管涡振是一种限幅振动，但由于其发生风速较低，振幅相对较大，会影响结构的强度和疲劳，因此大跨度拱桥的涡振响应研究具有重要的意义。
The coordinates of grids on the wing surface and dipole strength on the trailing vortex surface were changed with respect to time-stepping.
翼表面网格坐标和尾涡面上的偶极强度随时间步进变化。
The result shows that the measured strength of the vortex is not equal to the strength of the impulsive motion of the plate with a small angle of attack.
实验结果表明，由此测得的旋涡强度不同于用小攻角平板起动涡公式计算的起动涡强度。
