摘要
本文探求任意外形结构在外力作用下的瞬态声场特性,研究声辐射机理,用时域边界元技术讨论外力、结构振动响应和声辐射三者之间的关系,并用实验结果加以验证,为瞬态声振耦合研究提供一种新的数值分析方法。
This paper deals with the calculation of the transient sound radiation properties and the mechanism of sound radiation for an arbitrary shape three dimensional structure in time domain. It discusses theoretically and experimentally the relationship among external forces, vibration response and sound radiation, and provides a new numerical method of studying sound-vibration coupling properties and transient acoustic field.
