Presently most of the theoretical method to predict the propeller - induced hull pressure fluctuation is based on the calculation method in which the pressure is induced by pulsating source in infinite flow. the calculation method is adopted and the corresponded computer program is complied. the propeller - induced hull pressure fluctuation due to blade thickness, blade load, cavity thickness and the change of the cavity volume can be analyzed respectively in the computer program
目前，螺旋槳誘導的船體表面脈動壓力的理論預報方法，大多是以無限流場中點脈動源誘導的周圍流場的脈動壓力的計算方法為基礎的，本文採用該方法編制了計算程序，可以分別考慮槳葉厚度、槳葉負荷、槳葉上空泡厚度及其體積變化在船體表面指定位置上產生的脈動壓力。 -
By employing cole ' s classical theory of bubble dynamics, the motion of bubble produced by the underwater explosion and the corresponding bubble pulsating pressure are calculated. a profile function of the shock wave and its parameters are determined according to the principle of wave profile similitude and the equality of impulses. finally an analytic formula is derived to simulate the whole time history of the pressure from the front shock wave to the bubble pulsation, representing the fluid loadings of the underwater explosion
木文首先應用庫爾的經典水下爆炸氣泡運動理論計算出氣泡的運動和脈動的壓力波形，再依據波形相似的原則尋找波形模擬函數，用沖量相等的原則確定波形參數，得出了從沖擊波到氣泡脈動壓力整個過程對水下爆炸載荷進行模擬的解析公式。 -
