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 ,并附有算例
The differential equation of the lateral free vibration of a stepped disc with variable thickness is established and the initial parameter solution is obtained. In this paper, Rayleigh energy method is used to solve the transverse free vibration fundamental frequency of two-step variable thickness circular plate, with an example
