摘要
由单自由度系统中支承的运动规律及达朗伯原理得到运动微分方程,再利用线性系统的叠加原理分析系统中被支承质量的振幅及支承振幅、频率比和阻尼比间的关系,并通过图形对隔振方法进行了分析.
By means of superposition prin ciple of linear system and movement differential equation that is formulated according to d＇alembert＇s principle and law of support motion in a linear system,this paper analyses the relation between the supported amplitude and the support amplitude as well as the relation between frequency ratio and damping ratio. Moreover,it explores the methods to isolate vibration through specific analysis on drawing line.
