| 摘 要： | 本文利用动态子结构的加权残数法来计算大型电站锅炉炉墙的动力特性,使计算时处理的自由度数远小于有限元法,输入数据的总量大幅度下降,而其计算精度则与用大型通用有限元程序SAP5近于相同。

| Abstract: | In the present paper, the dynamic substructure synthesis combined with the weighted residual method is employed to determine the dynamic characteristics of boiler walls in large power plants. The number of degrees of freedom to be treated is far less than that in FEM. The amount of input data needed in computation decreases to a great extent while the computational accuracy is nearly the same as that obtained by the large current FEM program SAPS. |
