| 摘 要： | 对FGM斜板,通过坐标转换,在斜坐标系下建立了FGM斜板的横向振动微分方程。用微分求积法研究了四边简支和对边固支对边简支FGM斜板的自由振动特性,给出了不同角度和不同边长比下一阶固有频率与梯度指标之间的变化曲线,以及四边简支FGM斜板角度对固有频率的影响。

| Abstract: | A differential equation of motion for functionally graded material(FGM) skew plate is established in skew coordinate system.The vibration characteristics of FGM skew plate with four edges simply supported,two opposite edges clamped and other two edges simply supported are studied by differential quadrature method.The variation curves of the first-order natural frequency with gradient index for the different angles and different aspect ratios are obtained,and the effects of angles on natural frequency of FGM... |
