摘要
建立了阶梯式变厚度圆板横向自由振动的微分方程 ,得出其初参数解。文中用 Rayleigh能量法求解二级阶梯变厚度圆板横向自由振动基频 。
A differentinal equation of transverse free vibration is established for circular plates with stepped variable thickness,and the initial parameter solution of this equation is obtained.The fundamental frequencies of transverse free vibration for circular plates with 2 steped variable thickness are obtained by using Rayleigh energy method.
