摘要
采用挠度试函数 ,给出用Galerkin法求解Winkler弹性地基上四边自由的变厚度矩形板的自振频率方程和算式。
By means of the deflection function in document ,the formula for natural frequency of varying thickness rectangular plate with four free edges on Winkler elastic foundation are presented in the paper by the method of Galerkin,which is more effective for engineering calculation than others.
