| 摘 要： | 利用高斯数值积分方法,推导了方形活塞辐射阻抗的三重积分表达式,计算了方形活塞声源的辐射阻抗.结果表明,方形活塞的辐射阻抗是波数和活塞边长乘积的函数,系统在高频段向外辐射的声功率比低频段大,高频段同振质量比低频段小.

| Abstract: | Triple integral expression of the radiation impedance of square piston is deduced and the numerical results of the radiation impedance are calculated with the method of Gaussian numerical integral.It is shown that radiation impedance is a function of the product of wave number and side length,the sound power is greater and the adnexed mass is smaller in the higher frequency than those in the lower one respectively. |
