| 摘 要： | 对弹性结构的噪声分析过程中,结构表面的声学量很难精确求解,结构的形貌往往需要优化.利用声学分析软件SYSNOISE可以计算结构表面及任意点的辐射声场,提出了将有限元分析软件ANSYS得到的振动位移响应作为SYSNOISE的边界条件,从而准确得到结构表面各声学量,根据噪声分布,利用ANSYS优化结构形貌.通过实例,验证了...

| Abstract: | In the course of the noise analysis on the elastic structure,the acoustic volume of the structural surface is difficult to solve and its topography that requires optimization usually.Each point’s radiated sound field will be calculated in acoustic software of SYSNOISE.It is suggested that vibration displacement response obtained by ANSYS were taken as boundary condition of SYSNOISE,which can achieve accurate acoustic volume of the structure.And according to the noise distribution can optimize structure by ANSYS.The method is verified by the example. |
