| 摘 要： | 一种经过改进的完备模态型减缩法成功地本文提出来了。它有效地克服了原完备模态型减缩法不能保持自由结构之刚体特性的缺点，可是由ＩＣＭＲ法产生的减缩模型的弹性模态精度却不及ＣＭＲ法。

| Abstract: | An Improved Complete Mode-type Reduction (ICMR) method is developed successfully in this paper. ICMR can remove efficiently a shortcoming of CMR method, which is that null frequencies of the suspended (free) structures can not be retained in the reduced model obtained by CMR method. How-ever the precision of elastic modes given by ICMR is not as good as that by CMR. Thus it is suggested that CMR and ICMR should be applied to the restrained and suspended structures, respectively. |
