本文采用双向有限条将板划分成两组方向互相垂直的板条，采用满足边界条件的 梁函数组成相应节线的坐标函数，使节线的交点满足变位协调条件．在两组节线分割 成的各矩形域，由康斯曲面插值确定一点的变位，然后用瑞里－李兹法求解了板的动 力问题，并在ＩＢＭ上编制了相应的程序，若干算例表明这种算法比较准确、简便．
In this paper, the two-way finite strip is used to divide the plate into two groups of slats that are perpendicular to each other. The beam functions satisfying the boundary conditions are used to compose the coordinate function of the corresponding pitch line so that the intersection point of the pitch line meets the coordination condition of displacement. In the rectangular domains divided into two groups of pitch lines, one point of displacement is determined by the Cans’ surface interpolation, then the power problem of the plate is solved by the Rayleigh-Leeds method, and a corresponding program is compiled at IBM. The example shows that this algorithm is more accurate and simpler.
