摘要
本文提出采用直接法进行结构有限元动响应分析,克服了传统的振型迭加法及直接积分法确定误差精度的困难,该算法在微型机IBM—PC—XT上实现,算例表明,本文提出的方法计算效率较高。
We present a new procedure for the direct solution of the structure finite element dynamic equilibrium equations. It slove a difficulty how to control error accuracy in mode superposition and direct integration methods. In IBM-PC-XT computer we developed a program DDJDL3-W to realize this algorithm. The results show that it is of high computational efficiency.
