摘要
首先分析噪声控制工程的研究意义,指出噪声控制研究是环保的要求,是静音潜艇的设计、微机械的高精度加工等高技术的基础,是近代提高机器性能的一个革命性措施。接着,分析噪声控制工程的研究进展,提出噪声辐射理论研究,噪声测试与声源诊断,CAE、数值化与可视化研究,噪声的主动控制技术。最后,提出噪声控制工程的未来发展方向,即:声学禁带设计理论与方法,主动吸声,新型吸声材料的研究。
Firstly,research significance of noise control is analyzed in this paper and pointed out that noise control research is the need of environment, the basis of quiet submarine design, high precision machining of micro machine and revolutionary method to improve the present machine performance. Secondly, research development of noise control is analyzed and theory research of noise radiation, noise measurement and noise resource diagnosis, CAE, research of numerical value and visual analysis, noise active control are described in this paper. Finally, the future of noise active control is proposed, that is design theory and method of sound interdict strap,active sound absorption and research of new absorption material.
