【摘要】 本文根据水面船舶艉部结构的特点建立了螺旋桨脉动压力激励艉部结构的声辐射模型,推导了该模型的声辐射计算公式。并对典型船舶结构在四叶桨脉动压力作用下的辐射声进行数值计算,获得其远场辐射声。更多还原

【Abstract】 This paper is concerned with the problem of sound radiation from the body of surface ship derived by surface pulsative force of the propeller.The sound radiation model is established and the expression of far-field sound pressure is obtained therefore.Finally,the example of numeric result for typical ship with 4-blade propeller is given.更多还原
