摘要: 本文根据动力学普遍方程和单个自由度系统的自由振动规律,给出单个自由度系统自由振动到极端位置时的动力学表达式,可用来直接计算单个自由度系统的固有须率。

关键词: 振动, 自由度, 固有须率

Abstract: The expression of dynamics of single-degree-of-freedom systems vibra-
ting freely to the extreme position is derived in this paper from DAlem-
bert-Lagrange principle and vibrational behaviors of single-degree-of-free-
dom systems, It can be used directly to calculate natural frequencies of
single-degee-of-freedom systems

Key words: vibration, degree of freedom, natural frequency
