摘要
讨论了一种新型的计算振动体声辐射的方法──分布源边界点法．通过诸多算例，对分布源边界点法的计算精度、计算稳定性、适用范围和克服外部声辐射在特征频率处解的非唯一问题的可行性等进行了评价．
A new method, the distributed source boundary point method, used to calculate the acoustic radiation caused by vibrating body is discussed in this paper. The evaluation for the DSBPM iscarried out on the aspects of its calculating precision, calculating stability, scope of application as wellas its feasibility to overcome the non-unique solutions at characteristic frequencies for exterior acousticradiation through various examples.
