A study on the proposed scanlan linearity has discovered that if the self - excited loads and movement of the model and velocity constitute a linear relationship , and the model vibration accounts for a sine function of the frequency , the rate of the high - order harmonic waves should be quite small 考查了scanlan的線性假定:如果自激力與模型運(yùn)動的位移、速度成線性關(guān)系,模型振動是某一頻率的正弦函數(shù),那么相應(yīng)的自激力也應(yīng)是這一頻率的正弦函數(shù),高次諧波的分量應(yīng)極小。
