| 摘 要： | 对具有分布质量的层合板进行了强迫振动分析。分析了均布P_0e~(iω)ex~t激励作用下矩形组合板的横向动力响应。依据第三阶剪切变形理论对简支矩形板应用了Hamilton法则。采用双重Fourier级数对板位移进行假定。同时说明了质量部分的尺寸和位置,频率和质量比对板的影响。将分析结果与其他文献对无加载板的自由振动的分析结果进行对比,分析表明:具有很好的一致性。

| Abstract: | A forced vibration analysis of laminated composite plates carrying a distributed patch mass is analyzed and presented in this paper.It deals with the determination of the transverse,dynamic response of rectangular composite plates subjected to a uniformly distributed P_0e~(iω) ex~t-type excitation.The Hamilton's Principle,using third-order shear deformation theory,is applied to simply supported rectangular plates.The displacement of the plate is postulated by a double Fourier series.The effects of size and location of the area of the patch,frequency ratio and mass ratio on the response of the plate are also presented.A thorough comparison with well-known published results is presented for the case of free vibration of unloaded plates and good agreement is observed. |
