以单极子、偶极子和四极子声源为例,研究了在包围声源的四面体等腰三角形测量面上采用等腰三角形扫描路径应用扫描声强法测量声功率的收敛特性,并以扫描声强测量误差为目标函数,以等腰三角形扫描测量面的大小、测量面到声源的距离和扫描线密度为设计变量,应用遗传算法进行了优化.依此优化方法确定测量面的各几何参数,保证了测量精度,提高了测量效率,为快速准确地测量声功率提供了依据.

To measure the measuring surfaces of isosceles triangle from tetrahedron which surround sound source by the method of isosceles triangle path scanning, the monopole source, dipole source and quadrupole source are taken as examples. The scanning sound intensity method can get the convergent feature of sound power. The convergent feature is studied. The error analysis of scanning sound intensity as objective function, the design variable which made up of the sizeof scanning measuring surfaces of isosceles triangle, the distance between measuring surface and sound source, and the density of scanning line, all of which optimized by GA. This optimization determines the geometry parameters of measuring surface, ensures the measuring accuracy, also improves the measuring efficiency . They lays a solid foundation for swiftly and accurately measuring sound power of sound source.
