中文摘要:
      对噪声主动控制技术、杂交阻尼技术、压电分流阻尼技术及压电阻尼复合材料等方面的国内外研究概况进行了综述,通过现状分析,指出需要进一步发展成熟的流、固、声及电的多重耦合有限元分析方法;认为采用压电分流阻尼技术,以及与高分子阻尼材料及一些消声结构的结合,可以有效控制低频及宽频带噪声;压电阻尼复合材料的消声机制中,应该考虑微粒局域共振产生的消声作用,需进一步深入其基础理论。
英文摘要:
      The development of piezoelectric noise control technology in recent years,including active noise control,hybrid damping technology,piezoelectric shunting technology and piezoelectric damping composite materials etc,is reviewed.It is revealsed that the method of fluid,solid,sound and electric coupled multi-physics finite element should be further developed.Piezoelectric shunting technology and its combination with some polymer damping materials,or noise attenuation structures,can be effectively used to control low frequency and broad band noise.On piezoelectric damping composite materials,the local resonance of particles should be considered in its mechanism of noise attenuation,and the basic theory needs to be further studied.
