| Abstract: | The forced vibration of system structure of infinite freedom degree was usualy calculated with the method of mode analysis, and adopted the preceding n-th modal practicaly. The 0.6 method was used in this article which adopted preceding n-th modal aimed to achieve less n, high precision and simple error calculation. |
