【摘要】 从理论和试验两方面研究螺旋桨诱导的船尾激振力。用面元法作为基本理论方法,在螺旋桨和船尾上建立积分方程进行求解,通过迭代求解船尾和螺旋桨的相互影响。在试验中,将船尾简化为平板,在平板上布置5个测试点,将测得的离散值通过傅里叶变换得到各阶脉动压力。最后将计算结果和试验结果作了比较分析。更多还原

【Abstract】 Study the propeller exciting pressure of ship from theoretical and experimental expect.Use panel method as basic method,the integral equation founded on propeller and ship stem is solved.Hydrodynamic interaction between propeller and hull is achieved by iterative calculation.In the experiment,the stem is simplified as a flat,five test points are distributed on the flat.Discrete test results are transformed to amplitude according to blade frequency.The calculated result and experimental result are compared.更多还原
