基于动力学振动频率计算分析

Analysis of Vibration Frequency Calculation Based on Dynamic

利用达朗贝尔原理,对结构动力学中的多个质点中的单自由度振动体系分析,详细列解了这种频率计算方法,经过演算和逻辑推理而得出振动体系的频率计算一般适用的公式,该公式与单质点单自由度振动体系频率的计算公式具有相同的形式,这个公式也可用于很多种单自由度振动体系的有关自由度频率计算。

Used of d’Alembert’s principle to analyze the frequency of generalized single degree of freedom systems with multi-rigid-body and multi-particle. A formula for calculating the frequency of the systems is deduced, which is identical to that of systems with a particle. It can be suitable for generalized single degree of freedom systems at all kinds of status. It only needs to calculate the equivalent stiffness and the equivalent mass of the system.
