摘要
对受切向均布随从力作用的梯形薄板,用仿射变换及Ritz 法得到了各种边界条件下的特征值问题的通用数值算法,并计算出了5 种边界条件下菱形板的一阶自振频率及发散载荷.
Trapezoidal plates subjected to the uniformed follower forces are transformed to square plates by using coordinate transformation,and the eigenvalue problem are obtained by Ritz method.The general numerical computing method of eigenvalues with various boundary condition is presented,and the divergent load and natural frequency of rhombus plates with five boundary conditions are calculated.
