| Abstract: | 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. |
