| 摘 要： | 基于多自由度体系的惯性力方程，把最大惯性力加到体系质点位置，以此受力为依据，求出质点处的位移。根据各质点处位移变形协调条件，得出各质点处位移的相互关系，进而求出结构中质量的自振频率。此法对求解多自由度体系的自由振动，与传统方法相比具有方法简便、便于掌握等特点。

| Abstract: | Based on the inertia-force equation of multi-degree of freedom system,add the biggest inertia force to the position of mass-spring.Based on this state,the displacement of the mass-spring is given.According to the deformation compatibility condition,the co-relation of the mass-springs are obtained.Then the self-vibration frequency of multi-degree of freedom can be achieved.It is easy to solve the free vibration of the system of multi-degree of freedom.This method is not only portable but also easy to underst... |
