| 摘 要： | 首先根据结构动力修改的实际需要,在一般灵敏度基础上,提出了相对灵敏度概念.其次结合实例对传统的具有N自由度的特征灵敏度公式就其实用性和理论完备性进行了分析.最后对连续体如何进行灵敏度分析,提出了一种方法,并以倍捻锭子为例进行了计算.

| Abstract: | First, on the basis of the absolute sensitivities of natural frequencies and modal shapes, the concept of relative sensitivities have been advanced to meet the actual need for structural dynamic modification. Then, the conventional sensitivity formulas of natural frequencies for N - freedom system have been discussed on their practical applications and no - perfection in theory. The last, the structural dynamic sensitivities of the double twisting spindle have been analyzed through synthesis of component modes. |
