摘要
本文从声学振动理论出发,分析并导出了结构的振动与表面辐射噪声的关系。通过对6105QA柴油机油底壳的实验研究,证明这种关系是正确的。文中还论述了降低油底壳辐射噪声的控制方法。
In this paper, the relationship between the structure vibration and the surface noise radiation is analyzed and deduced from the acoustic and vibrational theory. And this relationship is proved through the experimental investigation of 6105QA diesel oil pan. It also discusses some control methods for reducing the radiated noise from oil pan.
