| 摘 要： | 本文研究在什么条件下可以不考虑主、次结构的耦联作用。文中以主次结构的质量比、刚度比作为参数,给出了不考虑耦联所引起的误差公式和利用这些公式计算结果所绘制的等误差线图。利用这些曲线可很方便地的估计不考虑耦联时的误差范围。

| Abstract: | A small auxiliary structure of a main structure is called sub-structure. Its vibration is coupled with main Structure. When the sub-structure is much smaller than the main structure, the coupling influence can be ignored. In this paper, we transform the continuous structure into equivalent two degrees of freedom system, the vibrations of the two degrees of freedom system are analysed in theory and computer. The conditions of ignorable coupling are discussed,the formulas and figures for estimating error are presented. |
