【摘要】 本文用有限差分法和加权残数法分析了反对称层合板的强迫振动问题,比较两数值分析手段所得到的近似解,取得令人满意的结果。通过电算,得到在各种不同无量纲载荷作用下的无量纲位移反应变化曲线,从而解决了反对称层合板在定常激振外载荷作用下的强迫振动问题。更多还原

【Abstract】 This paper uses the two methods-Finite Difference ant WeightedResidue-to analyse the problem of the forced vibration of unsymmetricallyIaminated anisotropic plates. By comparing the approximative solutions oflhese two numerical methods, we can come to the conclusion that thedifference between their results is little. Computer calculation helps todraw the nondimensional force-displacement curve. So this of paper solvesthe problem of the vibration of unsymmetrically laminated anisotropicplates due to the harmonic force.更多还原
