本文利用加权残数法中的离散型最小二乘法的混合法,分析了变刚度薄板的强度,试函数采用双重幂级数,提出了利用连接条件分析刚度发生突变的薄板强度的方法,通过一些算例证实了上述方法的可行性。
In this paper, the method of the discrete least square method in the weighted residual method is used to analyze the strength of the variable-strength thin plate. The trial function adopts the double power series, and the method of analyzing the stiffness of the thin plate with sudden changes in the connection conditions is proposed. The calculations demonstrate the feasibility of the above method.
