摘要
本文通过设计合理的内外存交换过程，改造有限元法、Ｌａｎｃｚｏｓ算法，从而使得对上万自由度的大型柔性空间结构的静动力计算可以在普通３８６微机上进行。
In this paper, the authors modify the FEM and Lanczos algorithm by designing proper incore/outcore processes for the corresponding matrix computation. By means of this, the computation on dynamic characteristics of large flexible space structures with DOFs up to more than 10,000 can be carried out in a general PC 386. Examples show that these approaches are right and efficient.
