An Approximate Analytical Method of the Nonlinear Vibroacoustic Coupling System 作者:Zhou, QZ (Zhou, Qizheng)[ 1 ] ; Wang, DS (Wang, Deshi)[ 1 ] ; Zhu, YY (Zhu, Yongyong)[ 1 ] SHOCK AND VIBRATION 文献号: 315416 DOI: 10.1155/2014/315416 出版年: 2014 查看期刊信息 摘要 An approximate analytical method of the nonlinear vibroacoustic coupling system is proposed for the first time. Taking the Duffing oscillator-plate-medium system as an example, the nonlinear vibroacoustic coupling equations are developed using variational principle. The two major difficulties which lie in solving the coupling equations are the uncertain motion of the oscillator and the surface acoustic pressure on the plate, a system for which the fluid-structure coupling cannot be neglected. Based on the incremental harmonic balance (IHB) method, the motion of the oscillator is expressed in the form of the Fourier series, and then the modal expression method and the incoherent assumption are employed to discretize the displacement and the surface pressure of the plate. Then the approximate analytical solution is given by the IHB method. The characteristics of acoustic radiation and surface quadratic velocity of the plate, the nonlinear characteristics of oscillator, and the influence of the excitation frequency and the nonlinear stiffness on the results are investigated by the numerical simulation. The results show that the excitation at the frequency close to the natural frequency of the oscillator can produce a significant response of the third-harmonic generation which determines the vibroacoustic characteristics of the plate. 关键词 KeyWords Plus:MUTUAL RADIATION RESISTANCES; HARMONIC-BALANCE METHOD; THIN ELASTIC PLATES; RECTANGULAR PLATE; VIBRATION; FORMULATION; FIELDS; PANELS; SOUND; POWER 作者信息 通讯作者地址: Zhou, QZ (通讯作者) Naval Univ Engn, Dept Weaponry Engn, Wuhan 430033, Peoples R China. 地址: [ 1 ] Naval Univ Engn, Dept Weaponry Engn, Wuhan 430033, Peoples R China 电子邮件地址:zqizheng@sina.cn 基金资助致谢 基金资助机构 授权号 National Natural Science Foundation of China 11372350 查看基金资助信息 出版商 HINDAWI PUBLISHING CORPORATION, 410 PARK AVENUE, 15TH FLOOR, #287 PMB, NEW YORK, NY 10022 USA 类别 / 分类 研究方向:Acoustics; Engineering; Mechanics Web of Science 类别:Acoustics; Engineering, Mechanical; Mechanics 文献信息 文献类型:Article 语种:English 入藏号: WOS:000336538900001 ISSN: 1070-9622 电子 ISSN: 1875-9203 期刊信息 [ 发自手机版 http://muchong.com/3g ] |
