摘要
结构动特性灵敏度在动力学结构修改和故障诊断中被广泛地应用。本文从能量观点出发推证了结构灵敏度表达式。表达形式物理意义明确，对某些工程应用问题可能更具有指导意义。
The structural dynamic characteristic sensitivity is widely applied to modification of the dynamic structure and the diagnose trouble. In this paper,an expression of thestructural dynamic characteristic sensitivity has been deduced in the view of energy. The expression is of an explicit physics meaning and probably of more guiding meaning for some applied engineering problems.
